molecular mass
Molecule's total weight
Molecular mass is the mass of a molecule, calculated by adding up the atomic masses of all its constituent atoms.
Water has a molecular mass of about 18 (two hydrogens at 1, one oxygen at 16).
The term is often used interchangeably with molecular weight, though mass is technically more precise.
Molecular mass helps chemists calculate how much of a substance to use in reactions.
