まず、CaFeMgMnSOCNNaKClAlBrUHReNaClCa(OH)2K4[Fe(CN)6]CuSO414CO 内の各原子の数を計算します。
Ca: 2, Fe: 2, Mg: 1, Mn: 1, S: 2, O: 8, C: 7, N: 7, Na: 2, K: 5, Cl: 2, Al: 1, Br: 1, U: 1, H: 3, Re: 1, Cu: 1, 14C: 1
次に、周期表の各元素の原子量を調べます。
Ca: 40.078, Fe: 55.845, Mg: 24.305, Mn: 54.938045, S: 32.065, O: 15.9994, C: 12.0107, N: 14.0067, Na: 22.98976928, K: 39.0983, Cl: 35.453, Al: 26.9815386, Br: 79.904, U: 238.02891, H: 1.00794, Re: 186.207, Cu: 63.546, 14C: 14.003241989
次に、原子数と原子量の積の合計を計算します。
モル質量 (CaFeMgMnSOCNNaKClAlBrUHReNaClCa(OH)2K4[Fe(CN)6]CuSO414CO) = ∑ Counti * Weighti =
Count(Ca) * Weight(Ca) + Count(Fe) * Weight(Fe) + Count(Mg) * Weight(Mg) + Count(Mn) * Weight(Mn) + Count(S) * Weight(S) + Count(O) * Weight(O) + Count(C) * Weight(C) + Count(N) * Weight(N) + Count(Na) * Weight(Na) + Count(K) * Weight(K) + Count(Cl) * Weight(Cl) + Count(Al) * Weight(Al) + Count(Br) * Weight(Br) + Count(U) * Weight(U) + Count(H) * Weight(H) + Count(Re) * Weight(Re) + Count(Cu) * Weight(Cu) + Count(14C) * Weight(14C) =
2 * 40.078 + 2 * 55.845 + 1 * 24.305 + 1 * 54.938045 + 2 * 32.065 + 8 * 15.9994 + 7 * 12.0107 + 7 * 14.0067 + 2 * 22.98976928 + 5 * 39.0983 + 2 * 35.453 + 1 * 26.9815386 + 1 * 79.904 + 1 * 238.02891 + 3 * 1.00794 + 1 * 186.207 + 1 * 63.546 + 1 * 14.003241989 =
1569.4076 g/mol
