次に、周期表の各元素の原子量を調べます。
Ca: 40.078, K: 39.0983, Ar: 39.948, Cl: 35.453, S: 32.065, P: 30.973762, Si: 28.0855, Mg: 24.305, Na: 22.98976928, Ne: 20.1797, F: 18.9984032, O: 15.9994, N: 14.0067, C: 12.0107, B: 10.811, Be: 9.012182, Li: 6.941, He: 4.002602, H: 1.00794
次に、原子数と原子量の積の合計を計算します。
モル質量 (CaKArClSPSiMgNaNeFONCBBeLiHeH) = ∑ Counti * Weighti =
Count(Ca) * Weight(Ca) + Count(K) * Weight(K) + Count(Ar) * Weight(Ar) + Count(Cl) * Weight(Cl) + Count(S) * Weight(S) + Count(P) * Weight(P) + Count(Si) * Weight(Si) + Count(Mg) * Weight(Mg) + Count(Na) * Weight(Na) + Count(Ne) * Weight(Ne) + Count(F) * Weight(F) + Count(O) * Weight(O) + Count(N) * Weight(N) + Count(C) * Weight(C) + Count(B) * Weight(B) + Count(Be) * Weight(Be) + Count(Li) * Weight(Li) + Count(He) * Weight(He) + Count(H) * Weight(H) =
1 * 40.078 + 1 * 39.0983 + 1 * 39.948 + 1 * 35.453 + 1 * 32.065 + 1 * 30.973762 + 1 * 28.0855 + 1 * 24.305 + 1 * 22.98976928 + 1 * 20.1797 + 1 * 18.9984032 + 1 * 15.9994 + 1 * 14.0067 + 1 * 12.0107 + 1 * 10.811 + 1 * 9.012182 + 1 * 6.941 + 1 * 4.002602 + 1 * 1.00794 =
405.9660 g/mol
