まず、HHeLiCBeBZnPuUIClFBrYPtRaXe 内の各原子の数を計算します。
H: 1, He: 1, Li: 1, C: 1, Be: 1, B: 1, Zn: 1, Pu: 1, U: 1, I: 1, Cl: 1, F: 1, Br: 1, Y: 1, Pt: 1, Ra: 1, Xe: 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, Li: 6.941, C: 12.0107, Be: 9.012182, B: 10.811, Zn: 65.38, Pu: 238.0495599, U: 238.02891, I: 126.90447, Cl: 35.453, F: 18.9984032, Br: 79.904, Y: 88.90585, Pt: 195.084, Ra: 226.0254098, Xe: 131.293
次に、原子数と原子量の積の合計を計算します。
モル質量 (HHeLiCBeBZnPuUIClFBrYPtRaXe) = ∑ Counti * Weighti =
Count(H) * Weight(H) + Count(He) * Weight(He) + Count(Li) * Weight(Li) + Count(C) * Weight(C) + Count(Be) * Weight(Be) + Count(B) * Weight(B) + Count(Zn) * Weight(Zn) + Count(Pu) * Weight(Pu) + Count(U) * Weight(U) + Count(I) * Weight(I) + Count(Cl) * Weight(Cl) + Count(F) * Weight(F) + Count(Br) * Weight(Br) + Count(Y) * Weight(Y) + Count(Pt) * Weight(Pt) + Count(Ra) * Weight(Ra) + Count(Xe) * Weight(Xe) =
1 * 1.00794 + 1 * 4.002602 + 1 * 6.941 + 1 * 12.0107 + 1 * 9.012182 + 1 * 10.811 + 1 * 65.38 + 1 * 238.0495599 + 1 * 238.02891 + 1 * 126.90447 + 1 * 35.453 + 1 * 18.9984032 + 1 * 79.904 + 1 * 88.90585 + 1 * 195.084 + 1 * 226.0254098 + 1 * 131.293 =
1487.8120 g/mol
