まず、KSCNBrPUCrZnHg4HHeOFXeEs 内の各原子の数を計算します。
K: 1, S: 1, C: 1, N: 1, Br: 1, P: 1, U: 1, Cr: 1, Zn: 1, Hg: 4, H: 1, He: 1, O: 1, F: 1, Xe: 1, Es: 1
次に、周期表の各元素の原子量を調べます。
K: 39.0983, S: 32.065, C: 12.0107, N: 14.0067, Br: 79.904, P: 30.973762, U: 238.02891, Cr: 51.9961, Zn: 65.38, Hg: 200.59, H: 1.00794, He: 4.002602, O: 15.9994, F: 18.9984032, Xe: 131.293, Es: 252.08298
次に、原子数と原子量の積の合計を計算します。
モル質量 (KSCNBrPUCrZnHg4HHeOFXeEs) = ∑ Counti * Weighti =
Count(K) * Weight(K) + Count(S) * Weight(S) + Count(C) * Weight(C) + Count(N) * Weight(N) + Count(Br) * Weight(Br) + Count(P) * Weight(P) + Count(U) * Weight(U) + Count(Cr) * Weight(Cr) + Count(Zn) * Weight(Zn) + Count(Hg) * Weight(Hg) + Count(H) * Weight(H) + Count(He) * Weight(He) + Count(O) * Weight(O) + Count(F) * Weight(F) + Count(Xe) * Weight(Xe) + Count(Es) * Weight(Es) =
1 * 39.0983 + 1 * 32.065 + 1 * 12.0107 + 1 * 14.0067 + 1 * 79.904 + 1 * 30.973762 + 1 * 238.02891 + 1 * 51.9961 + 1 * 65.38 + 4 * 200.59 + 1 * 1.00794 + 1 * 4.002602 + 1 * 15.9994 + 1 * 18.9984032 + 1 * 131.293 + 1 * 252.08298 =
1789.2078 g/mol
