まず、PbBiPoAtRnFlMcTsErTmYbLuFmMdNoLr 内の各原子の数を計算します。
Pb: 1, Bi: 1, Po: 1, At: 1, Rn: 1, Fl: 1, Mc: 1, Ts: 1, Er: 1, Tm: 1, Yb: 1, Lu: 1, Fm: 1, Md: 1, No: 1, Lr: 1
次に、周期表の各元素の原子量を調べます。
Pb: 207.2, Bi: 208.9804, Po: 208.9824304, At: 209.987148, Rn: 210.990601, Fl: 289.18728, Mc: 288.19249, Ts: 292.20755, Er: 167.259, Tm: 168.93421, Yb: 173.054, Lu: 174.9668, 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 (PbBiPoAtRnFlMcTsErTmYbLuFmMdNoLr) = ∑ Counti * Weighti =
Count(Pb) * Weight(Pb) + Count(Bi) * Weight(Bi) + Count(Po) * Weight(Po) + Count(At) * Weight(At) + Count(Rn) * Weight(Rn) + Count(Fl) * Weight(Fl) + Count(Mc) * Weight(Mc) + Count(Ts) * Weight(Ts) + Count(Er) * Weight(Er) + Count(Tm) * Weight(Tm) + Count(Yb) * Weight(Yb) + Count(Lu) * Weight(Lu) + Count(Fm) * Weight(Fm) + Count(Md) * Weight(Md) + Count(No) * Weight(No) + Count(Lr) * Weight(Lr) =
1 * 207.2 + 1 * 208.9804 + 1 * 208.9824304 + 1 * 209.987148 + 1 * 210.990601 + 1 * 289.18728 + 1 * 288.19249 + 1 * 292.20755 + 1 * 167.259 + 1 * 168.93421 + 1 * 173.054 + 1 * 174.9668 + 1 * 257.095105 + 1 * 258.098431 + 1 * 259.10103 + 1 * 262.10963 =
