Najpierw oblicz liczbę każdego atomu w FrRaAcThPaUNpPuAmCmBkCfEsFmMdNoLrRfDbSgBhHsMtDsRgCnNhFlMcOg:
Fr: 1, Ra: 1, Ac: 1, Th: 1, Pa: 1, U: 1, Np: 1, Pu: 1, Am: 1, Cm: 1, Bk: 1, Cf: 1, Es: 1, Fm: 1, Md: 1, No: 1, Lr: 1, Rf: 1, Db: 1, Sg: 1, Bh: 1, Hs: 1, Mt: 1, Ds: 1, Rg: 1, Cn: 1, Nh: 1, Fl: 1, Mc: 1, Og: 1
Następnie wyszukaj masy atomowe każdego pierwiastka w układzie okresowym :
Fr: 223.0197359, Ra: 226.0254098, Ac: 227.0277521, Th: 232.03806, Pa: 231.03588, U: 238.02891, Np: 236.04657, Pu: 238.0495599, Am: 241.0568291, Cm: 243.0613891, Bk: 247.070307, Cf: 249.0748535, Es: 252.08298, Fm: 257.095105, Md: 258.098431, No: 259.10103, Lr: 262.10963, Rf: 265.1167, Db: 268.12545, Sg: 271.13347, Bh: 272.13803, Hs: 270.13465, Mt: 276.15116, Ds: 281.16206, Rg: 280.16447, Cn: 285.17411, Nh: 284.17808, Fl: 289.18728, Mc: 288.19249, Og: 0
Teraz oblicz sumę iloczynów liczby atomów do masy atomowej:
Masa molowa (FrRaAcThPaUNpPuAmCmBkCfEsFmMdNoLrRfDbSgBhHsMtDsRgCnNhFlMcOg) = ∑ Counti * Weighti =
Count(Fr) * Weight(Fr) + Count(Ra) * Weight(Ra) + Count(Ac) * Weight(Ac) + Count(Th) * Weight(Th) + Count(Pa) * Weight(Pa) + Count(U) * Weight(U) + Count(Np) * Weight(Np) + Count(Pu) * Weight(Pu) + Count(Am) * Weight(Am) + Count(Cm) * Weight(Cm) + Count(Bk) * Weight(Bk) + Count(Cf) * Weight(Cf) + Count(Es) * Weight(Es) + Count(Fm) * Weight(Fm) + Count(Md) * Weight(Md) + Count(No) * Weight(No) + Count(Lr) * Weight(Lr) + Count(Rf) * Weight(Rf) + Count(Db) * Weight(Db) + Count(Sg) * Weight(Sg) + Count(Bh) * Weight(Bh) + Count(Hs) * Weight(Hs) + Count(Mt) * Weight(Mt) + Count(Ds) * Weight(Ds) + Count(Rg) * Weight(Rg) + Count(Cn) * Weight(Cn) + Count(Nh) * Weight(Nh) + Count(Fl) * Weight(Fl) + Count(Mc) * Weight(Mc) + Count(Og) * Weight(Og) =
1 * 223.0197359 + 1 * 226.0254098 + 1 * 227.0277521 + 1 * 232.03806 + 1 * 231.03588 + 1 * 238.02891 + 1 * 236.04657 + 1 * 238.0495599 + 1 * 241.0568291 + 1 * 243.0613891 + 1 * 247.070307 + 1 * 249.0748535 + 1 * 252.08298 + 1 * 257.095105 + 1 * 258.098431 + 1 * 259.10103 + 1 * 262.10963 + 1 * 265.1167 + 1 * 268.12545 + 1 * 271.13347 + 1 * 272.13803 + 1 * 270.13465 + 1 * 276.15116 + 1 * 281.16206 + 1 * 280.16447 + 1 * 285.17411 + 1 * 284.17808 + 1 * 289.18728 + 1 * 288.19249 + 1 * 0 =
7450.8804 g/mol
