What Is the Molar Mass of Gold? | Reference.com

The molar mass of gold is 196.97 g/mol. To find this number, multiply the atomic mass by the molar mass constant, which is one gram per one mole because gold in its elemental form is a single atom. Molar mass is a physical property of substances that describes the mass of a substance divided by the amount of the substance present.
