まず、CaFeZnKC18He29Bi3CfS3CHIW2B4XeArNeBh3Th3 内の各原子の数を計算します。
Ca: 1, Fe: 1, Zn: 1, K: 1, C: 19, He: 29, Bi: 3, Cf: 1, S: 3, H: 1, I: 1, W: 2, B: 4, Xe: 1, Ar: 1, Ne: 1, Bh: 3, Th: 3
次に、周期表の各元素の原子量を調べます。
Ca: 40.078, Fe: 55.845, Zn: 65.38, K: 39.0983, C: 12.0107, He: 4.002602, Bi: 208.9804, Cf: 249.0748535, S: 32.065, H: 1.00794, I: 126.90447, W: 183.84, B: 10.811, Xe: 131.293, Ar: 39.948, Ne: 20.1797, Bh: 272.13803, Th: 232.03806
次に、原子数と原子量の積の合計を計算します。
モル質量 (CaFeZnKC18He29Bi3CfS3CHIW2B4XeArNeBh3Th3) = ∑ Counti * Weighti =
Count(Ca) * Weight(Ca) + Count(Fe) * Weight(Fe) + Count(Zn) * Weight(Zn) + Count(K) * Weight(K) + Count(C) * Weight(C) + Count(He) * Weight(He) + Count(Bi) * Weight(Bi) + Count(Cf) * Weight(Cf) + Count(S) * Weight(S) + Count(H) * Weight(H) + Count(I) * Weight(I) + Count(W) * Weight(W) + Count(B) * Weight(B) + Count(Xe) * Weight(Xe) + Count(Ar) * Weight(Ar) + Count(Ne) * Weight(Ne) + Count(Bh) * Weight(Bh) + Count(Th) * Weight(Th) =
1 * 40.078 + 1 * 55.845 + 1 * 65.38 + 1 * 39.0983 + 19 * 12.0107 + 29 * 4.002602 + 3 * 208.9804 + 1 * 249.0748535 + 3 * 32.065 + 1 * 1.00794 + 1 * 126.90447 + 2 * 183.84 + 4 * 10.811 + 1 * 131.293 + 1 * 39.948 + 1 * 20.1797 + 3 * 272.13803 + 3 * 232.03806 =
3759.6765 g/mol
