まず、BrKrRbSrYZrNBMoTcRuRhPdAgCdINSNSBTeIXe 内の各原子の数を計算します。
Br: 1, Kr: 1, Rb: 1, Sr: 1, Y: 1, Zr: 1, N: 3, B: 2, Mo: 1, Tc: 1, Ru: 1, Rh: 1, Pd: 1, Ag: 1, Cd: 1, I: 2, S: 2, Te: 1, Xe: 1
次に、周期表の各元素の原子量を調べます。
Br: 79.904, Kr: 83.798, Rb: 85.4678, Sr: 87.62, Y: 88.90585, Zr: 91.224, N: 14.0067, B: 10.811, Mo: 95.96, Tc: 96.906365, Ru: 101.07, Rh: 102.9055, Pd: 106.42, Ag: 107.8682, Cd: 112.411, I: 126.90447, S: 32.065, Te: 127.6, 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 (BrKrRbSrYZrNBMoTcRuRhPdAgCdINSNSBTeIXe) = ∑ Counti * Weighti =
Count(Br) * Weight(Br) + Count(Kr) * Weight(Kr) + Count(Rb) * Weight(Rb) + Count(Sr) * Weight(Sr) + Count(Y) * Weight(Y) + Count(Zr) * Weight(Zr) + Count(N) * Weight(N) + Count(B) * Weight(B) + Count(Mo) * Weight(Mo) + Count(Tc) * Weight(Tc) + Count(Ru) * Weight(Ru) + Count(Rh) * Weight(Rh) + Count(Pd) * Weight(Pd) + Count(Ag) * Weight(Ag) + Count(Cd) * Weight(Cd) + Count(I) * Weight(I) + Count(S) * Weight(S) + Count(Te) * Weight(Te) + Count(Xe) * Weight(Xe) =
1 * 79.904 + 1 * 83.798 + 1 * 85.4678 + 1 * 87.62 + 1 * 88.90585 + 1 * 91.224 + 3 * 14.0067 + 2 * 10.811 + 1 * 95.96 + 1 * 96.906365 + 1 * 101.07 + 1 * 102.9055 + 1 * 106.42 + 1 * 107.8682 + 1 * 112.411 + 2 * 126.90447 + 2 * 32.065 + 1 * 127.6 + 1 * 131.293 =
