The mass (in atomic mass units) of one molecule of a compound is called?

Explanation:
The mass of a single molecule in atomic mass units is called molecular mass. It is found by adding the atomic masses of all atoms in the molecule, with each contribution in unified atomic mass units. For example, the molecular mass of water is 2×1 + 16 = 18 amu. This quantity is defined per molecule. Molar mass refers to the mass of one mole of molecules (grams per mole), so it would be 18 g/mol for water. Relative molecular mass is a dimensionless number equal to the molecular mass, and formula mass is used for formula units in compounds like salts. Therefore, the correct term for mass per molecule in amu is molecular mass.
