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. A mole is a unit of measurement used to express the amount of a chemical substance. When using moles, scientists will frequently use Avogadro's number, which defines the number of particles in a mole and is equal to approximately 6.022 × 10²³.
