для сжигания 2 моль водорода нужен 1 моль кислорода, следовательно, кислорода было в 2 раза меньше, чем водорода: 89,6/2= 44,8 л. V(O2) = 44.8 л. Т. к. в воздухе 21 % кислорода, то пропорцией находим V воздуха:
44,8 - 21 %
х - 100 %

х = (44,8 * 100)/21= 213,(3) Л
Ответ. V воздуха = 213,(3) Л

The country mouse liked the food very much.Soon they began their supper. But before they started to eat they heard some voices,the door opened and a man came in. The two mice ran into a narrow dark hole under the floor. Soon the door closed and the mice wanted to have their supper, but again they heard some voices,and the door opened again.

This was too much for the visitor. " Goodbye ", said the country mouse. " I am going home. I can see that you live in a rich house with a lot of food,but your home is a dangerous place. In my house i can enjoy my food,in your house i couldnt
