What is Molar Mass?
Molar mass (M) is the mass of a given substance divided by the amount of that substance, measured in grams per mole (g/mol). One mole contains exactly 6.02214076 × 10²³ elementary entities (Avogadro's number).
Frequently Asked Questions (FAQ)
Molecular weight is the ratio of the mass of a molecule to 1/12th the mass of carbon-12 (dimensionless or in unified atomic mass units, u). Molar mass has the unit g/mol.
Hydrates contain water molecules bound within their crystal structure. The molar mass is obtained by adding the mass of the anhydrous salt to the mass of the hydration water.
