次に、周期表の各元素の原子量を調べます。
Ho: 164.93032, Er: 167.259, Tm: 168.93421, Yb: 173.054, Lu: 174.9668, Ac: 227.0277521, Th: 232.03806, Pa: 231.03588, U: 238.02891, Np: 236.04657, Pu: 238.0495599, Am: 241.0568291, Cm: 243.0613891, Bk: 247.070307, Cf: 249.0748535, Es: 252.08298, Fm: 257.095105, Md: 258.098431, No: 259.10103, Lr: 262.10963
次に、原子数と原子量の積の合計を計算します。
モル質量 (HoErTmYbLuAcThPaUNpPuAmCmBkCfEsFmMdNoLr) = ∑ Counti * Weighti =
Count(Ho) * Weight(Ho) + Count(Er) * Weight(Er) + Count(Tm) * Weight(Tm) + Count(Yb) * Weight(Yb) + Count(Lu) * Weight(Lu) + Count(Ac) * Weight(Ac) + Count(Th) * Weight(Th) + Count(Pa) * Weight(Pa) + Count(U) * Weight(U) + Count(Np) * Weight(Np) + Count(Pu) * Weight(Pu) + Count(Am) * Weight(Am) + Count(Cm) * Weight(Cm) + Count(Bk) * Weight(Bk) + Count(Cf) * Weight(Cf) + Count(Es) * Weight(Es) + Count(Fm) * Weight(Fm) + Count(Md) * Weight(Md) + Count(No) * Weight(No) + Count(Lr) * Weight(Lr) =
