次に、原子数と原子量の積の合計を計算します。
モル質量 (FNiHeLiRaBaZnBSiSTlSbArKrXeRnFrScTiAt) = ∑ Counti * Weighti =
Count(F) * Weight(F) + Count(Ni) * Weight(Ni) + Count(He) * Weight(He) + Count(Li) * Weight(Li) + Count(Ra) * Weight(Ra) + Count(Ba) * Weight(Ba) + Count(Zn) * Weight(Zn) + Count(B) * Weight(B) + Count(Si) * Weight(Si) + Count(S) * Weight(S) + Count(Tl) * Weight(Tl) + Count(Sb) * Weight(Sb) + Count(Ar) * Weight(Ar) + Count(Kr) * Weight(Kr) + Count(Xe) * Weight(Xe) + Count(Rn) * Weight(Rn) + Count(Fr) * Weight(Fr) + Count(Sc) * Weight(Sc) + Count(Ti) * Weight(Ti) + Count(At) * Weight(At) =
1 * 18.9984032 + 1 * 58.6934 + 1 * 4.002602 + 1 * 6.941 + 1 * 226.0254098 + 1 * 137.327 + 1 * 65.38 + 1 * 10.811 + 1 * 28.0855 + 1 * 32.065 + 1 * 204.3833 + 1 * 121.76 + 1 * 39.948 + 1 * 83.798 + 1 * 131.293 + 1 * 210.990601 + 1 * 223.0197359 + 1 * 44.955912 + 1 * 47.867 + 1 * 209.987148 =
