まず、O1H1Be1Li1He1B1C1N1Cl1Ne1Au1Pu1Ru1U1Pt1Se1Pa1 内の各原子の数を計算します。
O: 1, H: 1, Be: 1, Li: 1, He: 1, B: 1, C: 1, N: 1, Cl: 1, Ne: 1, Au: 1, Pu: 1, Ru: 1, U: 1, Pt: 1, Se: 1, Pa: 1
次に、周期表の各元素の原子量を調べます。
O: 15.9994, H: 1.00794, Be: 9.012182, Li: 6.941, He: 4.002602, B: 10.811, C: 12.0107, N: 14.0067, Cl: 35.453, Ne: 20.1797, Au: 196.966569, Pu: 238.0495599, Ru: 101.07, U: 238.02891, Pt: 195.084, Se: 78.96, Pa: 231.03588
次に、原子数と原子量の積の合計を計算します。
モル質量 (O1H1Be1Li1He1B1C1N1Cl1Ne1Au1Pu1Ru1U1Pt1Se1Pa1) = ∑ Counti * Weighti =
Count(O) * Weight(O) + Count(H) * Weight(H) + Count(Be) * Weight(Be) + Count(Li) * Weight(Li) + Count(He) * Weight(He) + Count(B) * Weight(B) + Count(C) * Weight(C) + Count(N) * Weight(N) + Count(Cl) * Weight(Cl) + Count(Ne) * Weight(Ne) + Count(Au) * Weight(Au) + Count(Pu) * Weight(Pu) + Count(Ru) * Weight(Ru) + Count(U) * Weight(U) + Count(Pt) * Weight(Pt) + Count(Se) * Weight(Se) + Count(Pa) * Weight(Pa) =
1 * 15.9994 + 1 * 1.00794 + 1 * 9.012182 + 1 * 6.941 + 1 * 4.002602 + 1 * 10.811 + 1 * 12.0107 + 1 * 14.0067 + 1 * 35.453 + 1 * 20.1797 + 1 * 196.966569 + 1 * 238.0495599 + 1 * 101.07 + 1 * 238.02891 + 1 * 195.084 + 1 * 78.96 + 1 * 231.03588 =
