まず、LiBeNaMgKCaScSrYOsAlSbBiNCBFeRu 内の各原子の数を計算します。
Li: 1, Be: 1, Na: 1, Mg: 1, K: 1, Ca: 1, Sc: 1, Sr: 1, Y: 1, Os: 1, Al: 1, Sb: 1, Bi: 1, N: 1, C: 1, B: 1, Fe: 1, Ru: 1
次に、周期表の各元素の原子量を調べます。
Li: 6.941, Be: 9.012182, Na: 22.98976928, Mg: 24.305, K: 39.0983, Ca: 40.078, Sc: 44.955912, Sr: 87.62, Y: 88.90585, Os: 190.23, Al: 26.9815386, Sb: 121.76, Bi: 208.9804, N: 14.0067, C: 12.0107, B: 10.811, Fe: 55.845, Ru: 101.07
次に、原子数と原子量の積の合計を計算します。
モル質量 (LiBeNaMgKCaScSrYOsAlSbBiNCBFeRu) = ∑ Counti * Weighti =
Count(Li) * Weight(Li) + Count(Be) * Weight(Be) + Count(Na) * Weight(Na) + Count(Mg) * Weight(Mg) + Count(K) * Weight(K) + Count(Ca) * Weight(Ca) + Count(Sc) * Weight(Sc) + Count(Sr) * Weight(Sr) + Count(Y) * Weight(Y) + Count(Os) * Weight(Os) + Count(Al) * Weight(Al) + Count(Sb) * Weight(Sb) + Count(Bi) * Weight(Bi) + Count(N) * Weight(N) + Count(C) * Weight(C) + Count(B) * Weight(B) + Count(Fe) * Weight(Fe) + Count(Ru) * Weight(Ru) =
1 * 6.941 + 1 * 9.012182 + 1 * 22.98976928 + 1 * 24.305 + 1 * 39.0983 + 1 * 40.078 + 1 * 44.955912 + 1 * 87.62 + 1 * 88.90585 + 1 * 190.23 + 1 * 26.9815386 + 1 * 121.76 + 1 * 208.9804 + 1 * 14.0067 + 1 * 12.0107 + 1 * 10.811 + 1 * 55.845 + 1 * 101.07 =
1105.6014 g/mol
