How many atoms per mole
WebBecause the definitions of both the mole and the atomic mass unit are based on the same reference substance, 12 C, the molar mass of any substance is numerically equivalent to its atomic or formula weight in amu.Per the amu definition, a single 12 C atom weighs 12 amu (its atomic mass is 12 amu). According to the definition of the mole, 12 g of 12 C contains … WebFor example, theatomic mass of an oxygen atom is 16.00 amu; that means the molar massof an oxygen atom is 16.00 g/mol. Further, if you have 16.00 grams of oxygen atoms, you know from the definition of a mole that your sample contains 6.022 x 10 oxygen atoms. The concept of molar mass can also be applied to compounds.
