In chemistry, the molar mass M is a physical property defined as the mass of a given substance (chemical element or chemical compound) divided by the amount of substance. The base SI unit for molar mass is kg/mol. However, for historical reasons, molar masses are almost always expressed in g/mol.
Molar Mass is the mass of one mole of a substance (6.02 x 10 23 formula units). The unit for molar mass (note it is the mass of a mole) is grams/mole.Atomic Weight is the molar mass of an element. Formula Weight is the molar mass of an IONIC compound.Molecular Weight is the molar mass of a COVALENT compound.olar Mass is the mass of one mole of a substance (6.02 x 10 23 formula units). The unit for molar mass (note it is the mass of a mole) is grams/mole.
