次に、原子数と原子量の積の合計を計算します。
モル質量 (Na5Mg5Al5Si5P5S5Cl5Ar5K5Ca5Sc5Ti5V5Cr5Mn5Fe5Co5Ni5Cu5Zn5Ga5) = ∑ Counti * Weighti =
Count(Na) * Weight(Na) + Count(Mg) * Weight(Mg) + Count(Al) * Weight(Al) + Count(Si) * Weight(Si) + Count(P) * Weight(P) + Count(S) * Weight(S) + Count(Cl) * Weight(Cl) + Count(Ar) * Weight(Ar) + Count(K) * Weight(K) + Count(Ca) * Weight(Ca) + Count(Sc) * Weight(Sc) + Count(Ti) * Weight(Ti) + Count(V) * Weight(V) + Count(Cr) * Weight(Cr) + Count(Mn) * Weight(Mn) + Count(Fe) * Weight(Fe) + Count(Co) * Weight(Co) + Count(Ni) * Weight(Ni) + Count(Cu) * Weight(Cu) + Count(Zn) * Weight(Zn) + Count(Ga) * Weight(Ga) =
5 * 22.98976928 + 5 * 24.305 + 5 * 26.9815386 + 5 * 28.0855 + 5 * 30.973762 + 5 * 32.065 + 5 * 35.453 + 5 * 39.948 + 5 * 39.0983 + 5 * 40.078 + 5 * 44.955912 + 5 * 47.867 + 5 * 50.9415 + 5 * 51.9961 + 5 * 54.938045 + 5 * 55.845 + 5 * 58.933195 + 5 * 58.6934 + 5 * 63.546 + 5 * 65.38 + 5 * 69.723 =
