次に、原子数と原子量の積の合計を計算します。
モル質量 (HHeV(C7H7O2S)TiXeRaSNCOPLiINaClZnAgAuCu) = ∑ Counti * Weighti =
Count(H) * Weight(H) + Count(He) * Weight(He) + Count(V) * Weight(V) + Count(Ti) * Weight(Ti) + Count(Xe) * Weight(Xe) + Count(Ra) * Weight(Ra) + Count(S) * Weight(S) + Count(N) * Weight(N) + Count(C) * Weight(C) + Count(O) * Weight(O) + Count(P) * Weight(P) + Count(Li) * Weight(Li) + Count(I) * Weight(I) + Count(Na) * Weight(Na) + Count(Cl) * Weight(Cl) + Count(Zn) * Weight(Zn) + Count(Ag) * Weight(Ag) + Count(Au) * Weight(Au) + Count(Cu) * Weight(Cu) =
8 * 1.00794 + 1 * 4.002602 + 1 * 50.9415 + 1 * 47.867 + 1 * 131.293 + 1 * 226.0254098 + 2 * 32.065 + 1 * 14.0067 + 8 * 12.0107 + 3 * 15.9994 + 1 * 30.973762 + 1 * 6.941 + 1 * 126.90447 + 1 * 22.98976928 + 1 * 35.453 + 1 * 65.38 + 1 * 107.8682 + 1 * 196.966569 + 1 * 63.546 =
1347.4363 g/mol
