먼저 FeSiMgCOXeHCoAuPbPBrGdHeLiCaKSSbPdNiAsPoYYb에 있는 각 원자의 수를 계산합니다.
Fe: 1, Si: 1, Mg: 1, C: 1, O: 1, Xe: 1, H: 1, Co: 1, Au: 1, Pb: 1, P: 1, Br: 1, Gd: 1, He: 1, Li: 1, Ca: 1, K: 1, S: 1, Sb: 1, Pd: 1, Ni: 1, As: 1, Po: 1, Y: 1, Yb: 1
그런 다음 주기율표 의 각 원소에 대한 원자량을 검색합니다.
Fe: 55.845, Si: 28.0855, Mg: 24.305, C: 12.0107, O: 15.9994, Xe: 131.293, H: 1.00794, Co: 58.933195, Au: 196.966569, Pb: 207.2, P: 30.973762, Br: 79.904, Gd: 157.25, He: 4.002602, Li: 6.941, Ca: 40.078, K: 39.0983, S: 32.065, Sb: 121.76, Pd: 106.42, Ni: 58.6934, As: 74.9216, Po: 208.9824304, Y: 88.90585, Yb: 173.054
이제 원자 수와 원자량의 곱의 합을 계산합니다.
몰 질량 (FeSiMgCOXeHCoAuPbPBrGdHeLiCaKSSbPdNiAsPoYYb) = ∑ Counti * Weighti =
Count(Fe) * Weight(Fe) + Count(Si) * Weight(Si) + Count(Mg) * Weight(Mg) + Count(C) * Weight(C) + Count(O) * Weight(O) + Count(Xe) * Weight(Xe) + Count(H) * Weight(H) + Count(Co) * Weight(Co) + Count(Au) * Weight(Au) + Count(Pb) * Weight(Pb) + Count(P) * Weight(P) + Count(Br) * Weight(Br) + Count(Gd) * Weight(Gd) + Count(He) * Weight(He) + Count(Li) * Weight(Li) + Count(Ca) * Weight(Ca) + Count(K) * Weight(K) + Count(S) * Weight(S) + Count(Sb) * Weight(Sb) + Count(Pd) * Weight(Pd) + Count(Ni) * Weight(Ni) + Count(As) * Weight(As) + Count(Po) * Weight(Po) + Count(Y) * Weight(Y) + Count(Yb) * Weight(Yb) =
1 * 55.845 + 1 * 28.0855 + 1 * 24.305 + 1 * 12.0107 + 1 * 15.9994 + 1 * 131.293 + 1 * 1.00794 + 1 * 58.933195 + 1 * 196.966569 + 1 * 207.2 + 1 * 30.973762 + 1 * 79.904 + 1 * 157.25 + 1 * 4.002602 + 1 * 6.941 + 1 * 40.078 + 1 * 39.0983 + 1 * 32.065 + 1 * 121.76 + 1 * 106.42 + 1 * 58.6934 + 1 * 74.9216 + 1 * 208.9824304 + 1 * 88.90585 + 1 * 173.054 =
