m (C) - 25,4 г m (H) - 3,17 г m (O) - 33,86 г m (Cl) - 37,57 г
Вычислим количество вещества атомов каждого элемента по формуле
n = n/M n (C) = 25,4//12 г/моль = 2,12 моль
n (H) = 3,17/1 г/моль = 3,17 моль
n (o) = 33,86/16 г/моль = 2,12 моль
n (Cl) = 37,57 / 35,5 г/моль = 1,06 моль
Определим простейшую формулу - соотношение атомов
n (C) : n (H) : n (O) : n (Cl) = 2,12:3,17 : 2,12 : 1:06 = (каждое из этих чисел делим на наименьшее в данном случае на 1,06) = 2 : 3 : 2 : 1 Таким образом простейшая формула C2H3Cl O2

1.п (К) = 26.53/39 = 0.68
п (О) = 38.1/16=2.38
п (Сг) = 35.37/52=0.68
п (К) : п (Сг : п (О) = 0.68 : 0.68 : 2.38 = 2: 2: 7 Это бихромат калия К2Сг2О7
2. Для расчета возьмем 100 г вещества, тогда.
