次に、周期表の各元素の原子量を調べます。
C: 12.0107, H: 1.00794, Li: 6.941, Bi: 208.9804, Ra: 226.0254098, Ar: 39.948, S: 32.065, Nd: 144.242, As: 74.9216, He: 4.002602, Na: 22.98976928, Mg: 24.305, Mn: 54.938045, Hg: 200.59, Au: 196.966569, O: 15.9994, N: 14.0067
次に、原子数と原子量の積の合計を計算します。
モル質量 (CHCLi(ON)5BiRaArSCNdAs2He5AsNa5Mg5Mn5Hg2Au5) = ∑ Counti * Weighti =
Count(C) * Weight(C) + Count(H) * Weight(H) + Count(Li) * Weight(Li) + Count(Bi) * Weight(Bi) + Count(Ra) * Weight(Ra) + Count(Ar) * Weight(Ar) + Count(S) * Weight(S) + Count(Nd) * Weight(Nd) + Count(As) * Weight(As) + Count(He) * Weight(He) + Count(Na) * Weight(Na) + Count(Mg) * Weight(Mg) + Count(Mn) * Weight(Mn) + Count(Hg) * Weight(Hg) + Count(Au) * Weight(Au) + Count(O) * Weight(O) + Count(N) * Weight(N) =
3 * 12.0107 + 1 * 1.00794 + 1 * 6.941 + 1 * 208.9804 + 1 * 226.0254098 + 1 * 39.948 + 1 * 32.065 + 1 * 144.242 + 3 * 74.9216 + 5 * 4.002602 + 5 * 22.98976928 + 5 * 24.305 + 5 * 54.938045 + 2 * 200.59 + 5 * 196.966569 + 5 * 15.9994 + 5 * 14.0067 =
