The least stable of these are 165 Pt and 166 Pt, with half-lives of 260 µs, whereas the most stable is 193 Pt with a half-life of 50 years. However, platinum is often found with small quantities of other platinum family metals in deposits in Columbia, Ontario, the Ural Mountains, and in certain western US states. For other isotopes, the isotopic mass usually differs and is usually within 0.1 u of the mass number. The NIST manufactured the wires from platinum bar stock with a chemical purity of 99.999% by weight). [35] PtO2 and the less common PtO both decompose upon heating. Our final answer will be in grams of platinum, which is what we want. Most platinum isotopes decay by some combination of beta decay and alpha decay. [10][11] The metal has excellent resistance to corrosion, is stable at high temperatures and has stable electrical properties. Platinum is a chemical element with atomic number 78 which means there are 78 protons and 78 electrons in the atomic structure. Note: 1 mole of Pt have 6.022 x 10^23 number of atoms and 1 mole of Pt = 195.084 g. We could also say that 195.084 grams of Pt have 6.022 x 10^23 number of atoms. Antonio de Ulloa returned to Spain and established the first mineralogy lab in Spain and was the first to systematically study platinum, which was in 1748. The Cookies Statement is part of our Privacy Policy. Platinum is used as an alloying agent for various metal products, including fine wires, noncorrosive laboratory containers, medical instruments, dental prostheses, electrical contacts, and thermocouples. [51], The first European reference to platinum appears in 1557 in the writings of the Italian humanist Julius Caesar Scaliger as a description of an unknown noble metal found between Darién and Mexico, "which no fire nor any Spanish artifice has yet been able to liquefy". It was often simply thrown away, and there was an official decree forbidding the adulteration of gold with platinum impurities. [79] "Platinum awards" are the second highest possible, ranking above "gold", "silver" and "bronze", but below diamond. Because platinum is significantly denser than many of its impurities, the lighter impurities can be removed by simply floating them away in a liquid. , 32 ( 2017 ) , pp. [32] Platinum-based anodes are used in ships, pipelines, and steel piers. [25] In 1924, the geologist Hans Merensky discovered a large supply of platinum in the Bushveld Igneous Complex in South Africa. Platinum(IV) oxide, PtO2, also known as 'Adams' catalyst', is a black powder that is soluble in potassium hydroxide (KOH) solutions and concentrated acids. Element Platinum (Pt), Group 10, Atomic Number 78, d-block, Mass 195.084. Platinum particles chemically attach on to the oxygen and rise to the surface in a froth that is skimmed off for further refining. Watson F. R.

One mole of carbon is 6.022 x 10 23 atoms of carbon (Avogadro's number).This relation is then used to 'convert' a carbon atom to grams by the ratio: A2190-kg space station orbits earth at an altitude of 521000 m. find the magnitude of the force with which the space station attracts earth. [51], In 1735, Antonio de Ulloa and Jorge Juan y Santacilia saw Native Americans mining platinum while the Spaniards were travelling through Colombia and Peru for eight years. A collectible resource in Mass Effect: Andromeda. Pair up the Paladin with the Geth Trooper Soldier and you get very beautiful fire explosions. It is highly resistant to chemical attack. Platinum has molar mass 195.08g / mole and there is 1 atom in the compound or 65.017 %. We challenge the adage, "If it's worth doing, it's worth doing poorly." The Standard English unit is pounds mass per cubic foot (lbm/ft3). Molar mass of PtCl2(NH3)2 is 300.05 g / mol . It was the first British crown to be made of this particular metal. The SI base unit for amount of substance is the mole. [86] The misunderstanding is created by healthcare workers who are using inappropriately the name of the metal as a slang term for platinum-based chemotherapy medications like cisplatin. Platinum can also refer to the highest multiplayer difficulty setting introduced in the Mass Effect 3: Earth DLC. Answers: 1 Get Other questions on the subject: Physics. 1. 1) You may use almost everything for non-commercial and educational use. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. Platinum is primarily a collectible resource. Density is 22.5 g/cm^3. Platinum also has 34 synthetic isotopes ranging in atomic mass from 165 to 204, making the total number of known isotopes 40. Correspondingly, platinum is found in slightly higher abundances at sites of bolide impact on Earth that are associated with resulting post-impact volcanism, and can be mined economically; the Sudbury Basin is one such example. In 1752, Henrik Scheffer published a detailed scientific description of the metal, which he referred to as "white gold", including an account of how he succeeded in fusing platinum ore with the aid of arsenic. Next, I added the exponents, because it is a multiplcation problem and got 10^-1. Because it occurs naturally in the alluvial sands of various rivers, it was first used by pre-Columbian South American natives to produce artifacts. He succeeded in making malleable platinum by alloying it with gold, dissolving the alloy in hot aqua regia, precipitating the platinum with ammonium chloride, igniting the ammonium chloroplatinate, and hammering the resulting finely divided platinum to make it cohere. Once dried, the concentrated powder still contains less than 1% platinum. molecular weight of Platinum or grams The molecular formula for Platinum is Pt. [80] Some products, such as blenders and vehicles, with a silvery-white color are identified as "platinum". Franz Karl Achard made the first platinum crucible in 1784. Platinum is also used in the petroleum industry as a catalyst in a number of separate processes, but especially in catalytic reforming of straight-run naphthas into higher-octane gasoline that becomes rich in aromatic compounds. [13] It is also attacked by chlorine, bromine, iodine, and sulfur. [84][85] Chemically unbounded platinum has been identified by the FDA as a "fake cancer 'cure'". Molar mass of Pt = 195.078 g/mol. This table gives information about some radiosotopes of platinum, their masses, their half-lives, their modes of decay, their nuclear spins, and their nuclear magnetic moments. How many platinum atoms would there be in 274 milligrams of platinum? Here I'll do the work for you; copied from the "The Mass Effect 2 board FAQ of everything you're looking for" sticky: 2. [30], Platinum exists in higher abundances on the Moon and in meteorites. And so now that we have that, we can use the ah molecular mass of platinum one ninety five point zero eight grams per mall. A list of platinum deposits in Mass Effect. [62], Of the 218 tonnes of platinum sold in 2014, 98 tonnes were used for vehicle emissions control devices (45%), 74.7 tonnes for jewelry (34%), 20.0 tonnes for chemical production and petroleum refining (9.2%), and 5.85 tonnes for electrical applications such as hard disk drives (2.7%). [6] Compounds containing platinum, such as cisplatin, oxaliplatin and carboplatin, are applied in chemotherapy against certain types of cancer. A collectible resource in Mass Effect: Andromeda. [39], Zeise's salt, containing an ethylene ligand, was one of the first organometallic compounds discovered. [26][27] The large copper–nickel deposits near Norilsk in Russia, and the Sudbury Basin, Canada, are the two other large deposits. [78], Platinum's rarity as a metal has caused advertisers to associate it with exclusivity and wealth. Cooperite occurs in the Merensky Reef within the Bushveld complex, Gauteng, South Africa. One mole is 6.02 * 10^23 atoms. Ammonium chloroplatinate can be converted to platinum by heating. What is the mass of 6.0x10^23 platinum atoms?

However, platinum is often found with small quantities of other platinum family metals in deposits in Columbia, Ontario, the Ural Mountains, and in certain western US states. So moles cancel Adam's cancel on. Archeologists usually associate the tradition of platinum-working in South America with the La Tolita Culture (circa 600 BC – AD 200), but precise dates and location is difficult, as most platinum artifacts from the area were bought secondhand through the antiquities trade rather than obtained by direct archeological excavation. After publishing the report in 1748, Ulloa did not continue to investigate the new metal. How many platinum atoms would there be in 157 milligrams of platinum? Main purpose of this project is to help the public learn some interesting and important information about the peaceful uses of nuclear energy. Determination of the platinum concentration of a Pt/silica nanocomposite decorated with ultra-small Pt nanoparticles using single particle inductively coupled plasma mass spectrometry J. Anal. Not sure why my answer got a thumbs down. [9] Platinum(II,IV) oxide, Pt3O4, is formed in the following reaction: Unlike palladium acetate, platinum(II) acetate is not commercially available. The resulting gold–platinum alloy would then be soft enough to shape with tools. The mass of the new standard is then determined by comparison with the platinum-iridium working standards using the NBS-2 balance shown in Figure 5. Businesses often relinquish true growth potential and value add for saving time and resources - the affects of this initial decision compound over the life of the … The standard hydrogen electrode also uses a platinized platinum electrode due to its corrosion resistance, and other attributes. [63], The most common use of platinum is as a catalyst in chemical reactions, often as platinum black. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. Alloying this impure platinum residue called "plyoxen" with gold was the only solution at the time to obtain a pliable compound, but nowadays, very pure platinum is available and extremely long wires can be drawn from pure platinum, very easily, due to its crystalline structure, which is similar to that of many soft metals. The 1889 definition of the kilogram was simply the mass of the international prototype of the kilogram, an artefact made of platinum-iridium. Platinum is often found chemically uncombined as native platinum and as alloy with the other platinum-group metals and iron mostly.

C. Chaston, Platinum Metals Rev. [9] Platinum is more ductile than gold, silver or copper, thus being the most ductile of pure metals, but it is less malleable than gold. [37] Caesium platinide, Cs2Pt, a dark-red transparent crystalline compound[38] has been shown to contain Pt2− anions. It has been employed as a catalyst since the early 19th century, when platinum powder was used to catalyze the ignition of hydrogen. Physics, 21.06.2019 19:40, Maya629277. Platinum is a mineral resource. In this work, matrix assisted laser desorption ionization-time-of-flight (MALDI-TOF) mass spectrometry (MS) has been utilized to characterize colloidal platinum nanoparticles synthesized in the 1−4 nm size range. )[43][44], Dichloro(cycloocta-1,5-diene)platinum(II), Archaeologists have discovered traces of platinum in the gold used in ancient Egyptian burials as early as 1200 BC. Smaller reserves can be found in the United States,[27] for example in the Absaroka Range in Montana. [52], Platinum, along with the rest of the platinum-group metals, is obtained commercially as a by-product from nickel and copper mining and processing. In the 18th century, platinum's rarity made King Louis XV of France declare it the only metal fit for a king. Heating this ammonium salt in the presence of hydrogen reduces it to elemental platinum. Their assumptions could not be avoided because the platinum they experimented with was highly contaminated with minute amounts of platinum-family elements such as osmium and iridium, amongst others, which embrittled the platinum alloy. It is quite possible they did not recognize there was platinum in their gold. PtO2, also known as Adams' catalyst, is used as a hydrogenation catalyst, specifically for vegetable oils. Being a heavy metal, it leads to health problems upon exposure to its salts; but due to its corrosion resistance, metallic platinum has not been linked to adverse health effects. Gold prices are more stable in slow economic times, as gold is considered a safe haven. 996 - 1003 [48] To work the metal, they would combine gold and platinum powders by sintering. We report the highest to date mass activity among pure Pt catalysts for the ORR within similar size range. Platinum also has 34 synthetic isotopes ranging in atomic mass from 165 to 204, making the total number of known isotopes 40. Platinum finds use in jewellery, usually as a 90–95% alloy, due to its inertness. Dichloro(cycloocta-1,5-diene)platinum(II) is a commercially available olefin complex, which contains easily displaceable cod ligands ("cod" being an abbreviation of 1,5-cyclooctadiene). These two impurities are thus removed by running an electromagnet over the mixture. It is used for this purpose for its prestige and inherent bullion value. At Platinum, Alaska, about 17,000 kg (550,000 ozt) was mined between 1927 and 1975. Because of its scarcity in Earth's crust, only a few hundred tonnes are produced annually, and given its important uses, it is highly valuable and is a major precious metal commodity.[5]. In 1741, Charles Wood,[53] a British metallurgist, found various samples of Colombian platinum in Jamaica, which he sent to William Brownrigg for further investigation. Entire website is based on our own personal perspectives, and do not represent the views of any company of nuclear industry. Atomic mass of Platinum is 195.078 u. Our Website follows all legal requirements to protect your privacy. According to my periodic table, the mass of one mole of platinum is 195.08 grams . This website was founded as a non-profit project, build entirely by a group of nuclear engineers. Pure platinum has all the desirably properties except hardness. doi: 10.1371/journal.pone.0179000. [61] Mining and refining platinum has environmental impacts. For example, in the United States, a musical album that has sold more than 1 million copies will be credited as "platinum", whereas an album that has sold more than 10 million copies will be certified as "diamond". Platinum weighs 21.447 gram per cubic centimeter or 21 447 kilogram per cubic meter, i.e. This led him to believe he was working with a single metal, but in truth the ore still contained the yet-undiscovered platinum-group metals. This was, and still is, kept at the BIPM under the conditions specified by the 1st CGPM when it sanctioned the prototype and declared that "this prototype shall henceforth be considered to be the unit of mass". Weights of atoms and isotopes are from NIST article. Although gold is also used in industrial applications, especially in electronics due to its use as a conductor, its demand is not so driven by industrial uses. [21][22] It is sometimes mistaken for silver. Solved: Calculate the mass, in grams, of 0.063 moles of platinum. Equation: Reaktionstyp: Pt + … The mine ceased operations in 1990. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. During electrorefining of copper, noble metals such as silver, gold and the platinum-group metals as well as selenium and tellurium settle to the bottom of the cell as "anode mud", which forms the starting point for the extraction of the platinum-group metals. This started what is known as the "platinum age" in Spain. Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images. Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). This number, 12.01, is the mass in grams of one mole of carbon. [41] Others include carboplatin and oxaliplatin. They are platinum compounds not the metal itself. As is expected, tetracoordinate platinum(II) compounds tend to adopt 16-electron square planar geometries. When we use data that are related to certain product, we use only data released by public relations departments and allowed for use. PLoS One. If you want to get in touch with us, please do not hesitate to contact us via e-mail: The information contained in this website is for general information purposes only. Platinum can occur free in nature and is sometimes found in deposits of gold-bearing sands, primarily those found in the Ural mountains, Columbia and the western United States. Platinum (Pt) molar mass = 195.084 g/mol or some teachers tries to round it off to 195 g/mol. [42] (Side effects of cisplatin include nausea and vomiting, hair loss, tinnitus, hearing loss, and nephrotoxicity. It is then heated to over 2732F° (1500C°) in electric furnaces and the air is blown through again, removing iron and sulfur … It occurs in some nickel and copper ores along with some native deposits, mostly in South Africa, which accounts for 80% of the world production. By itself, it has various applications in photography, zinc etchings, indelible ink, plating, mirrors, porcelain coloring, and as a catalyst. Because platinum has a higher melting point than most other substances, many impurities can be burned or melted away without melting the platinum. (1 atom of platinum = 3.25x10^-22g) What I did was- (6.0x10^23)*(3.25x10-22g) ----> I multiplied the 6.0 and 3.25 and got 19.5. ES Eugene S. University of …
