次に、原子数と原子量の積の合計を計算します。
モル質量 (HHeLiBeBCOFNGePbAlClCrFeRnRfDbSrBaRa) = ∑ Counti * Weighti =
Count(H) * Weight(H) + Count(He) * Weight(He) + Count(Li) * Weight(Li) + Count(Be) * Weight(Be) + Count(B) * Weight(B) + Count(C) * Weight(C) + Count(O) * Weight(O) + Count(F) * Weight(F) + Count(N) * Weight(N) + Count(Ge) * Weight(Ge) + Count(Pb) * Weight(Pb) + Count(Al) * Weight(Al) + Count(Cl) * Weight(Cl) + Count(Cr) * Weight(Cr) + Count(Fe) * Weight(Fe) + Count(Rn) * Weight(Rn) + Count(Rf) * Weight(Rf) + Count(Db) * Weight(Db) + Count(Sr) * Weight(Sr) + Count(Ba) * Weight(Ba) + Count(Ra) * Weight(Ra) =
1 * 1.00794 + 1 * 4.002602 + 1 * 6.941 + 1 * 9.012182 + 1 * 10.811 + 1 * 12.0107 + 1 * 15.9994 + 1 * 18.9984032 + 1 * 14.0067 + 1 * 72.64 + 1 * 207.2 + 1 * 26.9815386 + 1 * 35.453 + 1 * 51.9961 + 1 * 55.845 + 1 * 210.990601 + 1 * 265.1167 + 1 * 268.12545 + 1 * 87.62 + 1 * 137.327 + 1 * 226.0254098 =
1738.1107 g/mol
