DescriptionThe molecular mass is the mass of a given molecule: it is measured in unified atomic mass units. Different molecules of the same compound may have different molecular masses because they contain different isotopes of an element.Formula unit mass is the sum of the atomic masses of all atoms present in a formula unit of a compound. It is calculated by adding the atomic masses of all the atoms present in one formula unit
