Molar mass is closely related to the relative molar mass (Mr) of a compound, to the older term formula weight (F.W.), and to the standard atomic masses of its constituent elements. However, it should be distinguished from the molecular mass (which is confusingly also sometimes known as molecular weight), which is the mass of one molecule (of any single isotopic composition) and is not directly related to the atomic mass, the mass of one atom (of any single isotope). The dalton, … WebThe molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, Mu = 0.999 999 999 65(30) × 10−3 kg⋅mol−1.
