The atomic mass is the average number of protons and neutrons for all natural isotopes of an element. The reason is that the molar mass of the substance affects the conversion. Either mass flow or mass concentration must be adhered to. This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes. 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. TA has more than 50 years of demonstrated success helping to scale growth companies around the world in our five core industries. For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass.
