次に、周期表の各元素の原子量を調べます。
As: 74.9216, B: 10.811, C: 12.0107, Er: 167.259, F: 18.9984032, Ga: 69.723, H: 1.00794, I: 126.90447, K: 39.0983, La: 138.90547, Mn: 54.938045, N: 14.0067, O: 15.9994, P: 30.973762, Ra: 226.0254098, S: 32.065, Ti: 47.867, U: 238.02891, V: 50.9415, D: 2.0141017778
次に、原子数と原子量の積の合計を計算します。
モル質量 (AsBCDErFGaHIKLaMnNOPRaSTiUV) = ∑ Counti * Weighti =
Count(As) * Weight(As) + Count(B) * Weight(B) + Count(C) * Weight(C) + Count(Er) * Weight(Er) + Count(F) * Weight(F) + Count(Ga) * Weight(Ga) + Count(H) * Weight(H) + Count(I) * Weight(I) + Count(K) * Weight(K) + Count(La) * Weight(La) + Count(Mn) * Weight(Mn) + Count(N) * Weight(N) + Count(O) * Weight(O) + Count(P) * Weight(P) + Count(Ra) * Weight(Ra) + Count(S) * Weight(S) + Count(Ti) * Weight(Ti) + Count(U) * Weight(U) + Count(V) * Weight(V) + Count(D) * Weight(D) =
1 * 74.9216 + 1 * 10.811 + 1 * 12.0107 + 1 * 167.259 + 1 * 18.9984032 + 1 * 69.723 + 1 * 1.00794 + 1 * 126.90447 + 1 * 39.0983 + 1 * 138.90547 + 1 * 54.938045 + 1 * 14.0067 + 1 * 15.9994 + 1 * 30.973762 + 1 * 226.0254098 + 1 * 32.065 + 1 * 47.867 + 1 * 238.02891 + 1 * 50.9415 + 1 * 2.0141017778 =
1372.4997 g/mol
