Сначала вычислите количество каждого атома в BCFHINOPKSWUVYAcAlAmSbArAsAtBaBkBeBiBhBrCdCaCfCeCsClCrCoCuCm:
B: 1, C: 1, F: 1, H: 1, I: 1, N: 1, O: 1, P: 1, K: 1, S: 1, W: 1, U: 1, V: 1, Y: 1, Ac: 1, Al: 1, Am: 1, Sb: 1, Ar: 1, As: 1, At: 1, Ba: 1, Bk: 1, Be: 1, Bi: 1, Bh: 1, Br: 1, Cd: 1, Ca: 1, Cf: 1, Ce: 1, Cs: 1, Cl: 1, Cr: 1, Co: 1, Cu: 1, Cm: 1
Затем найдите атомный вес для каждого элемента в таблице Менделеева :
B: 10.811, C: 12.0107, F: 18.9984032, H: 1.00794, I: 126.90447, N: 14.0067, O: 15.9994, P: 30.973762, K: 39.0983, S: 32.065, W: 183.84, U: 238.02891, V: 50.9415, Y: 88.90585, Ac: 227.0277521, Al: 26.9815386, Am: 241.0568291, Sb: 121.76, Ar: 39.948, As: 74.9216, At: 209.987148, Ba: 137.327, Bk: 247.070307, Be: 9.012182, Bi: 208.9804, Bh: 272.13803, Br: 79.904, Cd: 112.411, Ca: 40.078, Cf: 249.0748535, Ce: 140.116, Cs: 132.9054519, Cl: 35.453, Cr: 51.9961, Co: 58.933195, Cu: 63.546, Cm: 243.0613891
Теперь вычислите сумму произведений количества атомов на атомный вес:
Молярная масса (BCFHINOPKSWUVYAcAlAmSbArAsAtBaBkBeBiBhBrCdCaCfCeCsClCrCoCuCm) = ∑ Counti * Weighti =

1 * 10.811 + 1 * 12.0107 + 1 * 18.9984032 + 1 * 1.00794 + 1 * 126.90447 + 1 * 14.0067 + 1 * 15.9994 + 1 * 30.973762 + 1 * 39.0983 + 1 * 32.065 + 1 * 183.84 + 1 * 238.02891 + 1 * 50.9415 + 1 * 88.90585 + 1 * 227.0277521 + 1 * 26.9815386 + 1 * 241.0568291 + 1 * 121.76 + 1 * 39.948 + 1 * 74.9216 + 1 * 209.987148 + 1 * 137.327 + 1 * 247.070307 + 1 * 9.012182 + 1 * 208.9804 + 1 * 272.13803 + 1 * 79.904 + 1 * 112.411 + 1 * 40.078 + 1 * 249.0748535 + 1 * 140.116 + 1 * 132.9054519 + 1 * 35.453 + 1 * 51.9961 + 1 * 58.933195 + 1 * 63.546 + 1 * 243.0613891 =
3887.2817 g/mol
