モル質量 (H3Fe2U4AgNaXe9I20Au7Al2As5EsNe4Hg12Ra15TeTaW9Os17B5BeMg9) = ∑ Counti * Weighti =
Count(H) * Weight(H) + Count(Fe) * Weight(Fe) + Count(U) * Weight(U) + Count(Ag) * Weight(Ag) + Count(Na) * Weight(Na) + Count(Xe) * Weight(Xe) + Count(I) * Weight(I) + Count(Au) * Weight(Au) + Count(Al) * Weight(Al) + Count(As) * Weight(As) + Count(Es) * Weight(Es) + Count(Ne) * Weight(Ne) + Count(Hg) * Weight(Hg) + Count(Ra) * Weight(Ra) + Count(Te) * Weight(Te) + Count(Ta) * Weight(Ta) + Count(W) * Weight(W) + Count(Os) * Weight(Os) + Count(B) * Weight(B) + Count(Be) * Weight(Be) + Count(Mg) * Weight(Mg) =
3 * 1.00794 + 2 * 55.845 + 4 * 238.02891 + 1 * 107.8682 + 1 * 22.98976928 + 9 * 131.293 + 20 * 126.90447 + 7 * 196.966569 + 2 * 26.9815386 + 5 * 74.9216 + 1 * 252.08298 + 4 * 20.1797 + 12 * 200.59 + 15 * 226.0254098 + 1 * 127.6 + 1 * 180.94788 + 9 * 183.84 + 17 * 190.23 + 5 * 10.811 + 1 * 9.012182 + 9 * 24.305 =
