WebJul 1, 2014 · A mole of substance is equal to Avogadro's number (6.023×10 23) of that substance. The molar mass has units of g/mol or kg/mol. When using the unit g/mol, the numerical value of the molar mass of a molecule is the same as its average mass in daltons: Average mass of C: 12.011 Da. WebAug 8, 2024 · Units . The SI unit of molar volume is cubic meters per mole (m 3 /mol). However, because that is such a large volume, other units are usually used. Cubic centimeters per mole (cm 3 /mol) is used for solids and liquids. Cubic decimeters per mole (dm 3 /mol) may be used for gases.
