Najpierw oblicz liczbę każdego atomu w AlH3O3MnF7CCl4PSiNaMg10OsHgBBrIYZrUPoPrPaAmEsFmMdWTaTlCuZnPt:
Al: 1, H: 3, O: 3, Mn: 1, F: 7, C: 1, Cl: 4, P: 1, Si: 1, Na: 1, Mg: 10, Os: 1, Hg: 1, B: 1, Br: 1, I: 1, Y: 1, Zr: 1, U: 1, Po: 1, Pr: 1, Pa: 1, Am: 1, Es: 1, Fm: 1, Md: 1, W: 1, Ta: 1, Tl: 1, Cu: 1, Zn: 1, Pt: 1
Następnie wyszukaj masy atomowe każdego pierwiastka w układzie okresowym :
Al: 26.9815386, H: 1.00794, O: 15.9994, Mn: 54.938045, F: 18.9984032, C: 12.0107, Cl: 35.453, P: 30.973762, Si: 28.0855, Na: 22.98976928, Mg: 24.305, Os: 190.23, Hg: 200.59, B: 10.811, Br: 79.904, I: 126.90447, Y: 88.90585, Zr: 91.224, U: 238.02891, Po: 208.9824304, Pr: 140.90765, Pa: 231.03588, Am: 241.0568291, Es: 252.08298, Fm: 257.095105, Md: 258.098431, W: 183.84, Ta: 180.94788, Tl: 204.3833, Cu: 63.546, Zn: 65.38, Pt: 195.084
Teraz oblicz sumę iloczynów liczby atomów do masy atomowej:
Masa molowa (AlH3O3MnF7CCl4PSiNaMg10OsHgBBrIYZrUPoPrPaAmEsFmMdWTaTlCuZnPt) = ∑ Counti * Weighti =
Count(Al) * Weight(Al) + Count(H) * Weight(H) + Count(O) * Weight(O) + Count(Mn) * Weight(Mn) + Count(F) * Weight(F) + Count(C) * Weight(C) + Count(Cl) * Weight(Cl) + Count(P) * Weight(P) + Count(Si) * Weight(Si) + Count(Na) * Weight(Na) + Count(Mg) * Weight(Mg) + Count(Os) * Weight(Os) + Count(Hg) * Weight(Hg) + Count(B) * Weight(B) + Count(Br) * Weight(Br) + Count(I) * Weight(I) + Count(Y) * Weight(Y) + Count(Zr) * Weight(Zr) + Count(U) * Weight(U) + Count(Po) * Weight(Po) + Count(Pr) * Weight(Pr) + Count(Pa) * Weight(Pa) + Count(Am) * Weight(Am) + Count(Es) * Weight(Es) + Count(Fm) * Weight(Fm) + Count(Md) * Weight(Md) + Count(W) * Weight(W) + Count(Ta) * Weight(Ta) + Count(Tl) * Weight(Tl) + Count(Cu) * Weight(Cu) + Count(Zn) * Weight(Zn) + Count(Pt) * Weight(Pt) =
1 * 26.9815386 + 3 * 1.00794 + 3 * 15.9994 + 1 * 54.938045 + 7 * 18.9984032 + 1 * 12.0107 + 4 * 35.453 + 1 * 30.973762 + 1 * 28.0855 + 1 * 22.98976928 + 10 * 24.305 + 1 * 190.23 + 1 * 200.59 + 1 * 10.811 + 1 * 79.904 + 1 * 126.90447 + 1 * 88.90585 + 1 * 91.224 + 1 * 238.02891 + 1 * 208.9824304 + 1 * 140.90765 + 1 * 231.03588 + 1 * 241.0568291 + 1 * 252.08298 + 1 * 257.095105 + 1 * 258.098431 + 1 * 183.84 + 1 * 180.94788 + 1 * 204.3833 + 1 * 63.546 + 1 * 65.38 + 1 * 195.084 =
4253.8909 g/mol
