まず、AuAg3YPdBaH1He0HErUEsBKPtTiZnNH3ClBr 内の各原子の数を計算します。
Au: 1, Ag: 3, Y: 1, Pd: 1, Ba: 1, H: 5, He: 1, Er: 1, U: 1, Es: 1, B: 1, K: 1, Pt: 1, Ti: 1, Zn: 1, N: 1, Cl: 1, Br: 1
次に、周期表の各元素の原子量を調べます。
Au: 196.966569, Ag: 107.8682, Y: 88.90585, Pd: 106.42, Ba: 137.327, H: 1.00794, He: 4.002602, Er: 167.259, U: 238.02891, Es: 252.08298, B: 10.811, K: 39.0983, Pt: 195.084, Ti: 47.867, Zn: 65.38, N: 14.0067, Cl: 35.453, Br: 79.904
次に、原子数と原子量の積の合計を計算します。
モル質量 (AuAg3YPdBaH1He0HErUEsBKPtTiZnNH3ClBr) = ∑ Counti * Weighti =
Count(Au) * Weight(Au) + Count(Ag) * Weight(Ag) + Count(Y) * Weight(Y) + Count(Pd) * Weight(Pd) + Count(Ba) * Weight(Ba) + Count(H) * Weight(H) + Count(He) * Weight(He) + Count(Er) * Weight(Er) + Count(U) * Weight(U) + Count(Es) * Weight(Es) + Count(B) * Weight(B) + Count(K) * Weight(K) + Count(Pt) * Weight(Pt) + Count(Ti) * Weight(Ti) + Count(Zn) * Weight(Zn) + Count(N) * Weight(N) + Count(Cl) * Weight(Cl) + Count(Br) * Weight(Br) =
1 * 196.966569 + 3 * 107.8682 + 1 * 88.90585 + 1 * 106.42 + 1 * 137.327 + 5 * 1.00794 + 1 * 4.002602 + 1 * 167.259 + 1 * 238.02891 + 1 * 252.08298 + 1 * 10.811 + 1 * 39.0983 + 1 * 195.084 + 1 * 47.867 + 1 * 65.38 + 1 * 14.0067 + 1 * 35.453 + 1 * 79.904 =
2007.2412 g/mol
