The mole was defined in such a way that the molar mass of a compound, in g/mol, is numerically equal to the average mass of one molecule, in daltons. However, for historical reasons, molar masses are almost always expressed in g/mol. In the International System of Units (SI), the coherent unit of molar mass is kg/ mol.
The molar mass is an intensive property of the substance, that does not depend on the size of the sample. The formula weight is a synonym of molar mass that is frequently used for non-molecular compounds, such as ionic salts. The difference is that molecular mass is the mass of one specific particle or molecule, while the molar mass is an average over many particles or molecules. The molecular mass and formula mass are commonly used as a synonym of molar mass, particularly for molecular compounds however, the most authoritative sources define it differently. The molar mass is appropriate for converting between the mass of a substance and the amount of a substance for bulk quantities. Most commonly, the molar mass is computed from the standard atomic weights and is thus a terrestrial average and a function of the relative abundance of the isotopes of the constituent atoms on Earth. The molar mass is an average of many instances of the compound, which often vary in mass due to the presence of isotopes. The molar mass is a bulk, not molecular, property of a substance.
