まず、HLiNaKRbBeMgCaVTcRuOsIrBkCfEr 内の各原子の数を計算します。
H: 1, Li: 1, Na: 1, K: 1, Rb: 1, Be: 1, Mg: 1, Ca: 1, V: 1, Tc: 1, Ru: 1, Os: 1, Ir: 1, Bk: 1, Cf: 1, Er: 1
次に、周期表の各元素の原子量を調べます。
H: 1.00794, Li: 6.941, Na: 22.98976928, K: 39.0983, Rb: 85.4678, Be: 9.012182, Mg: 24.305, Ca: 40.078, V: 50.9415, Tc: 96.906365, Ru: 101.07, Os: 190.23, Ir: 192.217, Bk: 247.070307, Cf: 249.0748535, Er: 167.259
次に、原子数と原子量の積の合計を計算します。
モル質量 (HLiNaKRbBeMgCaVTcRuOsIrBkCfEr) = ∑ Counti * Weighti =
Count(H) * Weight(H) + Count(Li) * Weight(Li) + Count(Na) * Weight(Na) + Count(K) * Weight(K) + Count(Rb) * Weight(Rb) + Count(Be) * Weight(Be) + Count(Mg) * Weight(Mg) + Count(Ca) * Weight(Ca) + Count(V) * Weight(V) + Count(Tc) * Weight(Tc) + Count(Ru) * Weight(Ru) + Count(Os) * Weight(Os) + Count(Ir) * Weight(Ir) + Count(Bk) * Weight(Bk) + Count(Cf) * Weight(Cf) + Count(Er) * Weight(Er) =
1 * 1.00794 + 1 * 6.941 + 1 * 22.98976928 + 1 * 39.0983 + 1 * 85.4678 + 1 * 9.012182 + 1 * 24.305 + 1 * 40.078 + 1 * 50.9415 + 1 * 96.906365 + 1 * 101.07 + 1 * 190.23 + 1 * 192.217 + 1 * 247.070307 + 1 * 249.0748535 + 1 * 167.259 =
1523.6690 g/mol
