まず、WErRhAgAuTeFAtPmSmAmMnMoReUutBkRgK 内の各原子の数を計算します。
W: 1, Er: 1, Rh: 1, Ag: 1, Au: 1, Te: 1, F: 1, At: 1, Pm: 1, Sm: 1, Am: 1, Mn: 1, Mo: 1, Re: 1, Uut: 1, Bk: 1, Rg: 1, K: 1
次に、周期表の各元素の原子量を調べます。
W: 183.84, Er: 167.259, Rh: 102.9055, Ag: 107.8682, Au: 196.966569, Te: 127.6, F: 18.9984032, At: 209.987148, Pm: 144.912749, Sm: 150.36, Am: 241.0568291, Mn: 54.938045, Mo: 95.96, Re: 186.207, Uut: 284.17808, Bk: 247.070307, Rg: 280.16447, K: 39.0983
次に、原子数と原子量の積の合計を計算します。
モル質量 (WErRhAgAuTeFAtPmSmAmMnMoReUutBkRgK) = ∑ Counti * Weighti =
Count(W) * Weight(W) + Count(Er) * Weight(Er) + Count(Rh) * Weight(Rh) + Count(Ag) * Weight(Ag) + Count(Au) * Weight(Au) + Count(Te) * Weight(Te) + Count(F) * Weight(F) + Count(At) * Weight(At) + Count(Pm) * Weight(Pm) + Count(Sm) * Weight(Sm) + Count(Am) * Weight(Am) + Count(Mn) * Weight(Mn) + Count(Mo) * Weight(Mo) + Count(Re) * Weight(Re) + Count(Uut) * Weight(Uut) + Count(Bk) * Weight(Bk) + Count(Rg) * Weight(Rg) + Count(K) * Weight(K) =
1 * 183.84 + 1 * 167.259 + 1 * 102.9055 + 1 * 107.8682 + 1 * 196.966569 + 1 * 127.6 + 1 * 18.9984032 + 1 * 209.987148 + 1 * 144.912749 + 1 * 150.36 + 1 * 241.0568291 + 1 * 54.938045 + 1 * 95.96 + 1 * 186.207 + 1 * 284.17808 + 1 * 247.070307 + 1 * 280.16447 + 1 * 39.0983 =
2839.3706 g/mol
