まず、HCBNOHeNeFeMgWCuAuAgPbBaUEs 内の各原子の数を計算します。
H: 1, C: 1, B: 1, N: 1, O: 1, He: 1, Ne: 1, Fe: 1, Mg: 1, W: 1, Cu: 1, Au: 1, Ag: 1, Pb: 1, Ba: 1, U: 1, Es: 1
次に、周期表の各元素の原子量を調べます。
H: 1.00794, C: 12.0107, B: 10.811, N: 14.0067, O: 15.9994, He: 4.002602, Ne: 20.1797, Fe: 55.845, Mg: 24.305, W: 183.84, Cu: 63.546, Au: 196.966569, Ag: 107.8682, Pb: 207.2, Ba: 137.327, U: 238.02891, Es: 252.08298
次に、原子数と原子量の積の合計を計算します。
モル質量 (HCBNOHeNeFeMgWCuAuAgPbBaUEs) = ∑ Counti * Weighti =
Count(H) * Weight(H) + Count(C) * Weight(C) + Count(B) * Weight(B) + Count(N) * Weight(N) + Count(O) * Weight(O) + Count(He) * Weight(He) + Count(Ne) * Weight(Ne) + Count(Fe) * Weight(Fe) + Count(Mg) * Weight(Mg) + Count(W) * Weight(W) + Count(Cu) * Weight(Cu) + Count(Au) * Weight(Au) + Count(Ag) * Weight(Ag) + Count(Pb) * Weight(Pb) + Count(Ba) * Weight(Ba) + Count(U) * Weight(U) + Count(Es) * Weight(Es) =
1 * 1.00794 + 1 * 12.0107 + 1 * 10.811 + 1 * 14.0067 + 1 * 15.9994 + 1 * 4.002602 + 1 * 20.1797 + 1 * 55.845 + 1 * 24.305 + 1 * 183.84 + 1 * 63.546 + 1 * 196.966569 + 1 * 107.8682 + 1 * 207.2 + 1 * 137.327 + 1 * 238.02891 + 1 * 252.08298 =
1545.0277 g/mol
