Формулы:
n= m / M
V= 22.4 * n
Решение:
1) n (CuS) = 1/ 96 = 0.01 моль
2) n( CuS) = n( H2O) = 0.01 моль
3) V(H2O) = 0.01 * 22.4 = 0.224 литра
Ответ: V(H2O) = 0.224 литра

Fires that happen in the home are a very serious problem today. In America, there are over 100,000 home fires every year and many start in the kitchen. There are a lot of things you can do to protect your house from fire.
First of all, you need to follow a few safety rules. You should never leave the kitchen while you are cooking. It's also a bad idea to wear loose clothes when you cook. Always keep the cooking area clean and don't let children come very close to the cooker.
It is also important to know what to do if a fire starts. If a pan catches fire, don't throw water on it! Put a blanket over it and turn off the heat. If the fire doesn't go out, call the fire brigade. If a fire starts inside the oven, keep the door shut and turn it off. If you burn yourself, run cold water over the burn.
Finally, install a smoke alarm and learn how to use it. Also, know the number of your fire brigade by heart. It's better to be safe than sorry.
