次に、原子数と原子量の積の合計を計算します。
モル質量 (HHeLiBeBCNOFNeNaCaSWKUPAuAgBhSgLaLrAcPt) = ∑ Counti * Weighti =
Count(H) * Weight(H) + Count(He) * Weight(He) + Count(Li) * Weight(Li) + Count(Be) * Weight(Be) + Count(B) * Weight(B) + Count(C) * Weight(C) + Count(N) * Weight(N) + Count(O) * Weight(O) + Count(F) * Weight(F) + Count(Ne) * Weight(Ne) + Count(Na) * Weight(Na) + Count(Ca) * Weight(Ca) + Count(S) * Weight(S) + Count(W) * Weight(W) + Count(K) * Weight(K) + Count(U) * Weight(U) + Count(P) * Weight(P) + Count(Au) * Weight(Au) + Count(Ag) * Weight(Ag) + Count(Bh) * Weight(Bh) + Count(Sg) * Weight(Sg) + Count(La) * Weight(La) + Count(Lr) * Weight(Lr) + Count(Ac) * Weight(Ac) + Count(Pt) * Weight(Pt) =
1 * 1.00794 + 1 * 4.002602 + 1 * 6.941 + 1 * 9.012182 + 1 * 10.811 + 1 * 12.0107 + 1 * 14.0067 + 1 * 15.9994 + 1 * 18.9984032 + 1 * 20.1797 + 1 * 22.98976928 + 1 * 40.078 + 1 * 32.065 + 1 * 183.84 + 1 * 39.0983 + 1 * 238.02891 + 1 * 30.973762 + 1 * 196.966569 + 1 * 107.8682 + 1 * 272.13803 + 1 * 271.13347 + 1 * 138.90547 + 1 * 262.10963 + 1 * 227.0277521 + 1 * 195.084 =
2371.2765 g/mol
