まず、SeNBIrBaRbArSINC66NoAuAgCuO1YW 内の各原子の数を計算します。
Se: 1, N: 2, B: 1, Ir: 1, Ba: 1, Rb: 1, Ar: 1, S: 1, I: 1, C: 66, No: 1, Au: 1, Ag: 1, Cu: 1, O: 1, Y: 1, W: 1
次に、周期表の各元素の原子量を調べます。
Se: 78.96, N: 14.0067, B: 10.811, Ir: 192.217, Ba: 137.327, Rb: 85.4678, Ar: 39.948, S: 32.065, I: 126.90447, C: 12.0107, No: 259.10103, Au: 196.966569, Ag: 107.8682, Cu: 63.546, O: 15.9994, Y: 88.90585, W: 183.84
次に、原子数と原子量の積の合計を計算します。
モル質量 (SeNBIrBaRbArSINC66NoAuAgCuO1YW) = ∑ Counti * Weighti =
Count(Se) * Weight(Se) + Count(N) * Weight(N) + Count(B) * Weight(B) + Count(Ir) * Weight(Ir) + Count(Ba) * Weight(Ba) + Count(Rb) * Weight(Rb) + Count(Ar) * Weight(Ar) + Count(S) * Weight(S) + Count(I) * Weight(I) + Count(C) * Weight(C) + Count(No) * Weight(No) + Count(Au) * Weight(Au) + Count(Ag) * Weight(Ag) + Count(Cu) * Weight(Cu) + Count(O) * Weight(O) + Count(Y) * Weight(Y) + Count(W) * Weight(W) =
1 * 78.96 + 2 * 14.0067 + 1 * 10.811 + 1 * 192.217 + 1 * 137.327 + 1 * 85.4678 + 1 * 39.948 + 1 * 32.065 + 1 * 126.90447 + 66 * 12.0107 + 1 * 259.10103 + 1 * 196.966569 + 1 * 107.8682 + 1 * 63.546 + 1 * 15.9994 + 1 * 88.90585 + 1 * 183.84 =
2440.6469 g/mol
