次に、原子数と原子量の積の合計を計算します。
モル質量 (H96CoCdRaAsCmEsPaRnPoHgTlNaIBrC101N7Cl2S2O105) = ∑ Counti * Weighti =
Count(H) * Weight(H) + Count(Co) * Weight(Co) + Count(Cd) * Weight(Cd) + Count(Ra) * Weight(Ra) + Count(As) * Weight(As) + Count(Cm) * Weight(Cm) + Count(Es) * Weight(Es) + Count(Pa) * Weight(Pa) + Count(Rn) * Weight(Rn) + Count(Po) * Weight(Po) + Count(Hg) * Weight(Hg) + Count(Tl) * Weight(Tl) + Count(Na) * Weight(Na) + Count(I) * Weight(I) + Count(Br) * Weight(Br) + Count(C) * Weight(C) + Count(N) * Weight(N) + Count(Cl) * Weight(Cl) + Count(S) * Weight(S) + Count(O) * Weight(O) =
96 * 1.00794 + 1 * 58.933195 + 1 * 112.411 + 1 * 226.0254098 + 1 * 74.9216 + 1 * 243.0613891 + 1 * 252.08298 + 1 * 231.03588 + 1 * 210.990601 + 1 * 208.9824304 + 1 * 200.59 + 1 * 204.3833 + 1 * 22.98976928 + 1 * 126.90447 + 1 * 79.904 + 101 * 12.0107 + 7 * 14.0067 + 2 * 35.453 + 2 * 32.065 + 105 * 15.9994 =
5476.0789 g/mol
