먼저 NaLa2Cu3Ce3U2Ru3Pd5Al3Gd5Co5Au2Pu2TlZn3Th3Tm2Nb2Ta3Fe5Sb3In5에 있는 각 원자의 수를 계산합니다.
Na: 1, La: 2, Cu: 3, Ce: 3, U: 2, Ru: 3, Pd: 5, Al: 3, Gd: 5, Co: 5, Au: 2, Pu: 2, Tl: 1, Zn: 3, Th: 3, Tm: 2, Nb: 2, Ta: 3, Fe: 5, Sb: 3, In: 5
그런 다음 주기율표 의 각 원소에 대한 원자량을 검색합니다.
Na: 22.98976928, La: 138.90547, Cu: 63.546, Ce: 140.116, U: 238.02891, Ru: 101.07, Pd: 106.42, Al: 26.9815386, Gd: 157.25, Co: 58.933195, Au: 196.966569, Pu: 238.0495599, Tl: 204.3833, Zn: 65.38, Th: 232.03806, Tm: 168.93421, Nb: 92.90638, Ta: 180.94788, Fe: 55.845, Sb: 121.76, In: 114.818
이제 원자 수와 원자량의 곱의 합을 계산합니다.
몰 질량 (NaLa2Cu3Ce3U2Ru3Pd5Al3Gd5Co5Au2Pu2TlZn3Th3Tm2Nb2Ta3Fe5Sb3In5) = ∑ Counti * Weighti =
Count(Na) * Weight(Na) + Count(La) * Weight(La) + Count(Cu) * Weight(Cu) + Count(Ce) * Weight(Ce) + Count(U) * Weight(U) + Count(Ru) * Weight(Ru) + Count(Pd) * Weight(Pd) + Count(Al) * Weight(Al) + Count(Gd) * Weight(Gd) + Count(Co) * Weight(Co) + Count(Au) * Weight(Au) + Count(Pu) * Weight(Pu) + Count(Tl) * Weight(Tl) + Count(Zn) * Weight(Zn) + Count(Th) * Weight(Th) + Count(Tm) * Weight(Tm) + Count(Nb) * Weight(Nb) + Count(Ta) * Weight(Ta) + Count(Fe) * Weight(Fe) + Count(Sb) * Weight(Sb) + Count(In) * Weight(In) =
1 * 22.98976928 + 2 * 138.90547 + 3 * 63.546 + 3 * 140.116 + 2 * 238.02891 + 3 * 101.07 + 5 * 106.42 + 3 * 26.9815386 + 5 * 157.25 + 5 * 58.933195 + 2 * 196.966569 + 2 * 238.0495599 + 1 * 204.3833 + 3 * 65.38 + 3 * 232.03806 + 2 * 168.93421 + 2 * 92.90638 + 3 * 180.94788 + 5 * 55.845 + 3 * 121.76 + 5 * 114.818 =
