まず、NeCaFeAuAgOSCSeBrRuLiAlMgMnHNNaCl 内の各原子の数を計算します。
Ne: 1, Ca: 1, Fe: 1, Au: 1, Ag: 1, O: 1, S: 1, C: 1, Se: 1, Br: 1, Ru: 1, Li: 1, Al: 1, Mg: 1, Mn: 1, H: 1, N: 1, Na: 1, Cl: 1
次に、周期表の各元素の原子量を調べます。
Ne: 20.1797, Ca: 40.078, Fe: 55.845, Au: 196.966569, Ag: 107.8682, O: 15.9994, S: 32.065, C: 12.0107, Se: 78.96, Br: 79.904, Ru: 101.07, Li: 6.941, Al: 26.9815386, Mg: 24.305, Mn: 54.938045, H: 1.00794, N: 14.0067, Na: 22.98976928, Cl: 35.453
次に、原子数と原子量の積の合計を計算します。
モル質量 (NeCaFeAuAgOSCSeBrRuLiAlMgMnHNNaCl) = ∑ Counti * Weighti =
Count(Ne) * Weight(Ne) + Count(Ca) * Weight(Ca) + Count(Fe) * Weight(Fe) + Count(Au) * Weight(Au) + Count(Ag) * Weight(Ag) + Count(O) * Weight(O) + Count(S) * Weight(S) + Count(C) * Weight(C) + Count(Se) * Weight(Se) + Count(Br) * Weight(Br) + Count(Ru) * Weight(Ru) + Count(Li) * Weight(Li) + Count(Al) * Weight(Al) + Count(Mg) * Weight(Mg) + Count(Mn) * Weight(Mn) + Count(H) * Weight(H) + Count(N) * Weight(N) + Count(Na) * Weight(Na) + Count(Cl) * Weight(Cl) =
1 * 20.1797 + 1 * 40.078 + 1 * 55.845 + 1 * 196.966569 + 1 * 107.8682 + 1 * 15.9994 + 1 * 32.065 + 1 * 12.0107 + 1 * 78.96 + 1 * 79.904 + 1 * 101.07 + 1 * 6.941 + 1 * 26.9815386 + 1 * 24.305 + 1 * 54.938045 + 1 * 1.00794 + 1 * 14.0067 + 1 * 22.98976928 + 1 * 35.453 =
927.5696 g/mol
