с + o2 = co2

n(co2) = n(c) = (900*0,8)/12 = 60 моль; 0.8 - это часть чистого угля

v(co2) = 60 моль * 22,4 л/моль = 1344 л

ответ - 1344 л

mr(любого газа)=22,4 г/моль

v=mr*u=22,4*0,2=4,48 литра

                73 г                                         22,4 л

1. сначала определим чистую массу кислоты в растворе:

  m(hcl)=m(раствора)*w(hcl)=200*0,365=73 г

2. из уравнения видим,что при взаимодействии 73 г кислоты выделяется 22,4 л вдорода
