The molar mass of some substance is the mass in grams of one mole of that substance. This mass is given by the atomic weight of the chemical unit that makes up that substance in atomic mass units (amu). For example, gold has an atomic weight of 196.967 amu, so one mole of gold has a mass of 196.967 grams.
