Najpierw oblicz liczbę każdego atomu w HOCNURaThHgAuAlAgPoAsAtPSClLiBeFeCuKCaScYMnMgTiSrPbIArXeHeGe:
H: 1, O: 1, C: 1, N: 1, U: 1, Ra: 1, Th: 1, Hg: 1, Au: 1, Al: 1, Ag: 1, Po: 1, As: 1, At: 1, P: 1, S: 1, Cl: 1, Li: 1, Be: 1, Fe: 1, Cu: 1, K: 1, Ca: 1, Sc: 1, Y: 1, Mn: 1, Mg: 1, Ti: 1, Sr: 1, Pb: 1, I: 1, Ar: 1, Xe: 1, He: 1, Ge: 1
Następnie wyszukaj masy atomowe każdego pierwiastka w układzie okresowym :
H: 1.00794, O: 15.9994, C: 12.0107, N: 14.0067, U: 238.02891, Ra: 226.0254098, Th: 232.03806, Hg: 200.59, Au: 196.966569, Al: 26.9815386, Ag: 107.8682, Po: 208.9824304, As: 74.9216, At: 209.987148, P: 30.973762, S: 32.065, Cl: 35.453, Li: 6.941, Be: 9.012182, Fe: 55.845, Cu: 63.546, K: 39.0983, Ca: 40.078, Sc: 44.955912, Y: 88.90585, Mn: 54.938045, Mg: 24.305, Ti: 47.867, Sr: 87.62, Pb: 207.2, I: 126.90447, Ar: 39.948, Xe: 131.293, He: 4.002602, Ge: 72.64
Teraz oblicz sumę iloczynów liczby atomów do masy atomowej:
Masa molowa (HOCNURaThHgAuAlAgPoAsAtPSClLiBeFeCuKCaScYMnMgTiSrPbIArXeHeGe) = ∑ Counti * Weighti =
Count(H) * Weight(H) + Count(O) * Weight(O) + Count(C) * Weight(C) + Count(N) * Weight(N) + Count(U) * Weight(U) + Count(Ra) * Weight(Ra) + Count(Th) * Weight(Th) + Count(Hg) * Weight(Hg) + Count(Au) * Weight(Au) + Count(Al) * Weight(Al) + Count(Ag) * Weight(Ag) + Count(Po) * Weight(Po) + Count(As) * Weight(As) + Count(At) * Weight(At) + Count(P) * Weight(P) + Count(S) * Weight(S) + Count(Cl) * Weight(Cl) + Count(Li) * Weight(Li) + Count(Be) * Weight(Be) + Count(Fe) * Weight(Fe) + Count(Cu) * Weight(Cu) + Count(K) * Weight(K) + Count(Ca) * Weight(Ca) + Count(Sc) * Weight(Sc) + Count(Y) * Weight(Y) + Count(Mn) * Weight(Mn) + Count(Mg) * Weight(Mg) + Count(Ti) * Weight(Ti) + Count(Sr) * Weight(Sr) + Count(Pb) * Weight(Pb) + Count(I) * Weight(I) + Count(Ar) * Weight(Ar) + Count(Xe) * Weight(Xe) + Count(He) * Weight(He) + Count(Ge) * Weight(Ge) =
1 * 1.00794 + 1 * 15.9994 + 1 * 12.0107 + 1 * 14.0067 + 1 * 238.02891 + 1 * 226.0254098 + 1 * 232.03806 + 1 * 200.59 + 1 * 196.966569 + 1 * 26.9815386 + 1 * 107.8682 + 1 * 208.9824304 + 1 * 74.9216 + 1 * 209.987148 + 1 * 30.973762 + 1 * 32.065 + 1 * 35.453 + 1 * 6.941 + 1 * 9.012182 + 1 * 55.845 + 1 * 63.546 + 1 * 39.0983 + 1 * 40.078 + 1 * 44.955912 + 1 * 88.90585 + 1 * 54.938045 + 1 * 24.305 + 1 * 47.867 + 1 * 87.62 + 1 * 207.2 + 1 * 126.90447 + 1 * 39.948 + 1 * 131.293 + 1 * 4.002602 + 1 * 72.64 =
3009.0067 g/mol
