Secondary School. This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes. The atomic mass of a helium atom is 4.0026 u. For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100. The reason is that the molar mass of the substance affects the conversion.
