まず、NaMgHOClFFeZnHgAuAgPtLiCsFrXeKr 内の各原子の数を計算します。
Na: 1, Mg: 1, H: 1, O: 1, Cl: 1, F: 1, Fe: 1, Zn: 1, Hg: 1, Au: 1, Ag: 1, Pt: 1, Li: 1, Cs: 1, Fr: 1, Xe: 1, Kr: 1
次に、周期表の各元素の原子量を調べます。
Na: 22.98976928, Mg: 24.305, H: 1.00794, O: 15.9994, Cl: 35.453, F: 18.9984032, Fe: 55.845, Zn: 65.38, Hg: 200.59, Au: 196.966569, Ag: 107.8682, Pt: 195.084, Li: 6.941, Cs: 132.9054519, Fr: 223.0197359, Xe: 131.293, Kr: 83.798
次に、原子数と原子量の積の合計を計算します。
モル質量 (NaMgHOClFFeZnHgAuAgPtLiCsFrXeKr) = ∑ Counti * Weighti =
Count(Na) * Weight(Na) + Count(Mg) * Weight(Mg) + Count(H) * Weight(H) + Count(O) * Weight(O) + Count(Cl) * Weight(Cl) + Count(F) * Weight(F) + Count(Fe) * Weight(Fe) + Count(Zn) * Weight(Zn) + Count(Hg) * Weight(Hg) + Count(Au) * Weight(Au) + Count(Ag) * Weight(Ag) + Count(Pt) * Weight(Pt) + Count(Li) * Weight(Li) + Count(Cs) * Weight(Cs) + Count(Fr) * Weight(Fr) + Count(Xe) * Weight(Xe) + Count(Kr) * Weight(Kr) =
1 * 22.98976928 + 1 * 24.305 + 1 * 1.00794 + 1 * 15.9994 + 1 * 35.453 + 1 * 18.9984032 + 1 * 55.845 + 1 * 65.38 + 1 * 200.59 + 1 * 196.966569 + 1 * 107.8682 + 1 * 195.084 + 1 * 6.941 + 1 * 132.9054519 + 1 * 223.0197359 + 1 * 131.293 + 1 * 83.798 =
