WebMolecular Weight. Molecules are composed of several atoms, for example a carbon dioxide molecule (CO 2) is made up of 1 carbon atom and 2 oxygen atoms.The molecular weight (or molecular mass or relative molecular mass (RMM)) is the sum of the atomic weights of all the atoms in the molecule.. Example 1. Calculate the molecular weight of … WebMolecular mass ( molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12) Molar mass ( molar weight) is the mass of one mole of a substance and is expressed in g/mol. Weights of atoms and isotopes are from NIST article .
