次に、周期表の各元素の原子量を調べます。
H: 1.00794, O: 15.9994, Cl: 35.453, Au: 196.966569, Ag: 107.8682, Hg: 200.59, Pb: 207.2, Ar: 39.948, Ne: 20.1797, He: 4.002602, Ce: 140.116, Br: 79.904, Cu: 63.546, Fe: 55.845, K: 39.0983, P: 30.973762, V: 50.9415, I: 126.90447, C: 12.0107, Zn: 65.38, Ir: 192.217
次に、原子数と原子量の積の合計を計算します。
モル質量 (HOClAuAgHgPbAuArNeHeCeBrCuFeKPOVICZnIr) = ∑ Counti * Weighti =
Count(H) * Weight(H) + Count(O) * Weight(O) + Count(Cl) * Weight(Cl) + Count(Au) * Weight(Au) + Count(Ag) * Weight(Ag) + Count(Hg) * Weight(Hg) + Count(Pb) * Weight(Pb) + Count(Ar) * Weight(Ar) + Count(Ne) * Weight(Ne) + Count(He) * Weight(He) + Count(Ce) * Weight(Ce) + Count(Br) * Weight(Br) + Count(Cu) * Weight(Cu) + Count(Fe) * Weight(Fe) + Count(K) * Weight(K) + Count(P) * Weight(P) + Count(V) * Weight(V) + Count(I) * Weight(I) + Count(C) * Weight(C) + Count(Zn) * Weight(Zn) + Count(Ir) * Weight(Ir) =
1 * 1.00794 + 2 * 15.9994 + 1 * 35.453 + 2 * 196.966569 + 1 * 107.8682 + 1 * 200.59 + 1 * 207.2 + 1 * 39.948 + 1 * 20.1797 + 1 * 4.002602 + 1 * 140.116 + 1 * 79.904 + 1 * 63.546 + 1 * 55.845 + 1 * 39.0983 + 1 * 30.973762 + 1 * 50.9415 + 1 * 126.90447 + 1 * 12.0107 + 1 * 65.38 + 1 * 192.217 =
1899.1181 g/mol
