次に、原子数と原子量の積の合計を計算します。
モル質量 (AlCl3K2Cr2O7CH3COONaKMnO4UO2CClF3HeNeArKrXeRnCO2Ag9Br18Hg5) = ∑ Counti * Weighti =
Count(Al) * Weight(Al) + Count(Cl) * Weight(Cl) + Count(K) * Weight(K) + Count(Cr) * Weight(Cr) + Count(O) * Weight(O) + Count(C) * Weight(C) + Count(H) * Weight(H) + Count(Na) * Weight(Na) + Count(Mn) * Weight(Mn) + Count(U) * Weight(U) + Count(F) * Weight(F) + Count(He) * Weight(He) + Count(Ne) * Weight(Ne) + Count(Ar) * Weight(Ar) + Count(Kr) * Weight(Kr) + Count(Xe) * Weight(Xe) + Count(Rn) * Weight(Rn) + Count(Ag) * Weight(Ag) + Count(Br) * Weight(Br) + Count(Hg) * Weight(Hg) =
1 * 26.9815386 + 4 * 35.453 + 3 * 39.0983 + 2 * 51.9961 + 17 * 15.9994 + 4 * 12.0107 + 3 * 1.00794 + 1 * 22.98976928 + 1 * 54.938045 + 1 * 238.02891 + 3 * 18.9984032 + 1 * 4.002602 + 1 * 20.1797 + 1 * 39.948 + 1 * 83.798 + 1 * 131.293 + 1 * 210.990601 + 9 * 107.8682 + 18 * 79.904 + 5 * 200.59 =
4988.3367 g/mol
