Mass of a gold atom in grams
Web20 de sept. de 2024 · 2nd answer : Don't be confused, these are the old names of moles of these things. 1 gram atom means 1 mole of atoms 1 gram molecule means 1 mole of molecules 1 gram ion means 1 mole of ions. Similarly, 2 gram atom means 2 moles of atoms. So, this is the name of mole. WebAvogadro's number is the ratio of the mass of 12 grams of carbon-12 to the mass of 1 atom of carbon-12 measured in grams. Or, a little easier to understand, Avogadro's number is the ratio of 1 gram to 1 atomic mass unit but with the atomic mass unit expressed in grams. Thus, Avogadro's number has been measured to be 6.022141×10²³.
