Вот тебе пример с барием, а то если я решу, ты не разберешься. 
Если что уравнение такое: 2Li+2H2O=2LiOH+H2

Какое количество бария нужно взять, чтобы при его взаимодействии с 1 л воды образовался 2%-ный раствор гидроксида бария?

Решение. Барий растворяется в воде по уравнению

Пусть в реакцию вступило х моль Ва, тогда образовалось по x моль Ва(ОН)2 (М=171) и Н2. Масса вещества Ва(ОН)2 в растворе составляет 171x, а масса раствора равна:

m(р-ра) = 1000 + m(Ba) - m(Н2) = 1000 +137x – 2x = 1000+135x.

Массовая доля гидроксида бария равна:

ω(Ва(ОН)2) =171x / (1000 +135x) = 0,02.

oткуда х = 0,119.

ответ. 0,119 моль Ва.

73 г                                                                                 Х л

2HCl            +       Na2CO3       =         2NaCl        +      CO2    +     H2O

n = 2 моль                                                                    n = 1 моль

Mr = 36 г/моль                                                            Vm = 22,4 л/моль

m = 72 г                                                                       V = 22,4 л

73 г HCl    -    Х л СО2

72 г HCl    -    22,4 л СО2

V(CO2) = 73 * 22,4 / 72 = 22,7 л
