まず、HHeCNFNePSClArSeBrKrIXeRn 内の各原子の数を計算します。
H: 1, He: 1, C: 1, N: 1, F: 1, Ne: 1, P: 1, S: 1, Cl: 1, Ar: 1, Se: 1, Br: 1, Kr: 1, I: 1, Xe: 1, Rn: 1
次に、周期表の各元素の原子量を調べます。
H: 1.00794, He: 4.002602, C: 12.0107, N: 14.0067, F: 18.9984032, Ne: 20.1797, P: 30.973762, S: 32.065, Cl: 35.453, Ar: 39.948, Se: 78.96, Br: 79.904, Kr: 83.798, I: 126.90447, Xe: 131.293, Rn: 210.990601
次に、原子数と原子量の積の合計を計算します。
モル質量 (HHeCNFNePSClArSeBrKrIXeRn) = ∑ Counti * Weighti =
Count(H) * Weight(H) + Count(He) * Weight(He) + Count(C) * Weight(C) + Count(N) * Weight(N) + Count(F) * Weight(F) + Count(Ne) * Weight(Ne) + Count(P) * Weight(P) + Count(S) * Weight(S) + Count(Cl) * Weight(Cl) + Count(Ar) * Weight(Ar) + Count(Se) * Weight(Se) + Count(Br) * Weight(Br) + Count(Kr) * Weight(Kr) + Count(I) * Weight(I) + Count(Xe) * Weight(Xe) + Count(Rn) * Weight(Rn) =
1 * 1.00794 + 1 * 4.002602 + 1 * 12.0107 + 1 * 14.0067 + 1 * 18.9984032 + 1 * 20.1797 + 1 * 30.973762 + 1 * 32.065 + 1 * 35.453 + 1 * 39.948 + 1 * 78.96 + 1 * 79.904 + 1 * 83.798 + 1 * 126.90447 + 1 * 131.293 + 1 * 210.990601 =
