まず、C14H14N3NaO3SIBSeUThFrRbKLiAsSb 内の各原子の数を計算します。
C: 14, H: 14, N: 3, Na: 1, O: 3, S: 1, I: 1, B: 1, Se: 1, U: 1, Th: 1, Fr: 1, Rb: 1, K: 1, Li: 1, As: 1, Sb: 1
次に、周期表の各元素の原子量を調べます。
C: 12.0107, H: 1.00794, N: 14.0067, Na: 22.98976928, O: 15.9994, S: 32.065, I: 126.90447, B: 10.811, Se: 78.96, U: 238.02891, Th: 232.03806, Fr: 223.0197359, Rb: 85.4678, K: 39.0983, Li: 6.941, As: 74.9216, Sb: 121.76
次に、原子数と原子量の積の合計を計算します。
モル質量 (C14H14N3NaO3SIBSeUThFrRbKLiAsSb) = ∑ Counti * Weighti =
Count(C) * Weight(C) + Count(H) * Weight(H) + Count(N) * Weight(N) + Count(Na) * Weight(Na) + Count(O) * Weight(O) + Count(S) * Weight(S) + Count(I) * Weight(I) + Count(B) * Weight(B) + Count(Se) * Weight(Se) + Count(U) * Weight(U) + Count(Th) * Weight(Th) + Count(Fr) * Weight(Fr) + Count(Rb) * Weight(Rb) + Count(K) * Weight(K) + Count(Li) * Weight(Li) + Count(As) * Weight(As) + Count(Sb) * Weight(Sb) =
14 * 12.0107 + 14 * 1.00794 + 3 * 14.0067 + 1 * 22.98976928 + 3 * 15.9994 + 1 * 32.065 + 1 * 126.90447 + 1 * 10.811 + 1 * 78.96 + 1 * 238.02891 + 1 * 232.03806 + 1 * 223.0197359 + 1 * 85.4678 + 1 * 39.0983 + 1 * 6.941 + 1 * 74.9216 + 1 * 121.76 =
1565.2849 g/mol
