まず、BCHHeIKLiLuNNeOPSScThUXeY 内の各原子の数を計算します。
B: 1, C: 1, H: 1, He: 1, I: 1, K: 1, Li: 1, Lu: 1, N: 1, Ne: 1, O: 1, P: 1, S: 1, Sc: 1, Th: 1, U: 1, Xe: 1, Y: 1
次に、周期表の各元素の原子量を調べます。
B: 10.811, C: 12.0107, H: 1.00794, He: 4.002602, I: 126.90447, K: 39.0983, Li: 6.941, Lu: 174.9668, N: 14.0067, Ne: 20.1797, O: 15.9994, P: 30.973762, S: 32.065, Sc: 44.955912, Th: 232.03806, U: 238.02891, Xe: 131.293, Y: 88.90585
次に、原子数と原子量の積の合計を計算します。
モル質量 (BCHHeIKLiLuNNeOPSScThUXeY) = ∑ Counti * Weighti =
Count(B) * Weight(B) + Count(C) * Weight(C) + Count(H) * Weight(H) + Count(He) * Weight(He) + Count(I) * Weight(I) + Count(K) * Weight(K) + Count(Li) * Weight(Li) + Count(Lu) * Weight(Lu) + Count(N) * Weight(N) + Count(Ne) * Weight(Ne) + Count(O) * Weight(O) + Count(P) * Weight(P) + Count(S) * Weight(S) + Count(Sc) * Weight(Sc) + Count(Th) * Weight(Th) + Count(U) * Weight(U) + Count(Xe) * Weight(Xe) + Count(Y) * Weight(Y) =
1 * 10.811 + 1 * 12.0107 + 1 * 1.00794 + 1 * 4.002602 + 1 * 126.90447 + 1 * 39.0983 + 1 * 6.941 + 1 * 174.9668 + 1 * 14.0067 + 1 * 20.1797 + 1 * 15.9994 + 1 * 30.973762 + 1 * 32.065 + 1 * 44.955912 + 1 * 232.03806 + 1 * 238.02891 + 1 * 131.293 + 1 * 88.90585 =
1224.1891 g/mol
