まず、Bi8Os4Pb2TlHgAuPtIrReWTaUPaThBaCs 内の各原子の数を計算します。
Bi: 8, Os: 4, Pb: 2, Tl: 1, Hg: 1, Au: 1, Pt: 1, Ir: 1, Re: 1, W: 1, Ta: 1, U: 1, Pa: 1, Th: 1, Ba: 1, Cs: 1
次に、周期表の各元素の原子量を調べます。
Bi: 208.9804, Os: 190.23, Pb: 207.2, Tl: 204.3833, Hg: 200.59, Au: 196.966569, Pt: 195.084, Ir: 192.217, Re: 186.207, W: 183.84, Ta: 180.94788, U: 238.02891, Pa: 231.03588, Th: 232.03806, Ba: 137.327, Cs: 132.9054519
次に、原子数と原子量の積の合計を計算します。
モル質量 (Bi8Os4Pb2TlHgAuPtIrReWTaUPaThBaCs) = ∑ Counti * Weighti =
Count(Bi) * Weight(Bi) + Count(Os) * Weight(Os) + Count(Pb) * Weight(Pb) + Count(Tl) * Weight(Tl) + Count(Hg) * Weight(Hg) + Count(Au) * Weight(Au) + Count(Pt) * Weight(Pt) + Count(Ir) * Weight(Ir) + Count(Re) * Weight(Re) + Count(W) * Weight(W) + Count(Ta) * Weight(Ta) + Count(U) * Weight(U) + Count(Pa) * Weight(Pa) + Count(Th) * Weight(Th) + Count(Ba) * Weight(Ba) + Count(Cs) * Weight(Cs) =
8 * 208.9804 + 4 * 190.23 + 2 * 207.2 + 1 * 204.3833 + 1 * 200.59 + 1 * 196.966569 + 1 * 195.084 + 1 * 192.217 + 1 * 186.207 + 1 * 183.84 + 1 * 180.94788 + 1 * 238.02891 + 1 * 231.03588 + 1 * 232.03806 + 1 * 137.327 + 1 * 132.9054519 =
