次に、原子数と原子量の積の合計を計算します。
モル質量 (CHFeFAuAgMgNClOSHeEuKrSrMgNaRaRbCrVWV) = ∑ Counti * Weighti =
Count(C) * Weight(C) + Count(H) * Weight(H) + Count(Fe) * Weight(Fe) + Count(F) * Weight(F) + Count(Au) * Weight(Au) + Count(Ag) * Weight(Ag) + Count(Mg) * Weight(Mg) + Count(N) * Weight(N) + Count(Cl) * Weight(Cl) + Count(O) * Weight(O) + Count(S) * Weight(S) + Count(He) * Weight(He) + Count(Eu) * Weight(Eu) + Count(Kr) * Weight(Kr) + Count(Sr) * Weight(Sr) + Count(Na) * Weight(Na) + Count(Ra) * Weight(Ra) + Count(Rb) * Weight(Rb) + Count(Cr) * Weight(Cr) + Count(V) * Weight(V) + Count(W) * Weight(W) =
1 * 12.0107 + 1 * 1.00794 + 1 * 55.845 + 1 * 18.9984032 + 1 * 196.966569 + 1 * 107.8682 + 2 * 24.305 + 1 * 14.0067 + 1 * 35.453 + 1 * 15.9994 + 1 * 32.065 + 1 * 4.002602 + 1 * 151.964 + 1 * 83.798 + 1 * 87.62 + 1 * 22.98976928 + 1 * 226.0254098 + 1 * 85.4678 + 1 * 51.9961 + 2 * 50.9415 + 1 * 183.84 =
1538.4176 g/mol
