Molecular mass is the sum of the masses of the component atoms of a molecule. For most molecules, this mass is in the range of 10ˉ²⁷ to 10ˉ²⁵ kg. Molar mass is the mass of one mole of some substance; it is expressed in grams per mole.

Explanation:
Molar mass and molecular weight are often confused, but their values are very different. Molar mass is the mass of one mole of a substance, while molecular weight is the mass of one molecule of a substance. One mole is the number of particles, such as atoms, molecules, ions or electrons, in a substance. The key to the difference between molar mass and molecular weight is the difference between a mole and a molecule.
