10 Facts About Molar mass

The molar mass is a bulk, not molecular, property of a substance.

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 appropriate for converting between the mass of a substance and the amount of a substance for bulk quantities.

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.

Formula weight is a synonym of molar mass that is frequently used for non-molecular compounds, such as ionic salts.

Molar mass is an intensive property of the substance, that does not depend on the size of the sample.

Chemical elements without isolated molecules, such as carbon and metals, the molar mass is computed dividing by the number of moles of atoms instead.

Gram atomic Molar mass is another term for the Molar mass, in grams, of one mole of atoms of that element.

Molecular Molar mass is the Molar mass of a given molecule: it is usually measured in daltons.

Precision to which a molar mass is known depends on the precision of the atomic masses from which it was calculated, and value of the molar mass constant.
