次に、周期表の各元素の原子量を調べます。
C: 12.0107, Br: 79.904, Cl: 35.453, Xe: 131.293, Kr: 83.798, At: 209.987148, Ra: 226.0254098, Th: 232.03806, Uuo: 0, Pb: 207.2, Rg: 280.16447, Ds: 281.16206, Os: 190.23, Sg: 271.13347, Np: 236.04657, U: 238.02891, Pa: 231.03588, Yb: 173.054
次に、原子数と原子量の積の合計を計算します。
モル質量 (CBrClXeKrAtRaThUuoPbRgDsOsSgNpUPaThYb) = ∑ Counti * Weighti =
Count(C) * Weight(C) + Count(Br) * Weight(Br) + Count(Cl) * Weight(Cl) + Count(Xe) * Weight(Xe) + Count(Kr) * Weight(Kr) + Count(At) * Weight(At) + Count(Ra) * Weight(Ra) + Count(Th) * Weight(Th) + Count(Uuo) * Weight(Uuo) + Count(Pb) * Weight(Pb) + Count(Rg) * Weight(Rg) + Count(Ds) * Weight(Ds) + Count(Os) * Weight(Os) + Count(Sg) * Weight(Sg) + Count(Np) * Weight(Np) + Count(U) * Weight(U) + Count(Pa) * Weight(Pa) + Count(Yb) * Weight(Yb) =
1 * 12.0107 + 1 * 79.904 + 1 * 35.453 + 1 * 131.293 + 1 * 83.798 + 1 * 209.987148 + 1 * 226.0254098 + 2 * 232.03806 + 1 * 0 + 1 * 207.2 + 1 * 280.16447 + 1 * 281.16206 + 1 * 190.23 + 1 * 271.13347 + 1 * 236.04657 + 1 * 238.02891 + 1 * 231.03588 + 1 * 173.054 =
