Question
A gas cylinder can hold 1 kg of hydrogen at room temperature and pressure. If the number of molecules of hydrogen in the cylinder is X, calculate the number of carbon dioxide molecules in the cylinder. State the law that helped you to arrive at the result.
Solution
According to Avogadro's law, "equal volumes of all gases under similar conditions of temperature and pressure contain the same number of molecules."
∴ Number of molecules of carbon dioxide in the cylinder = number of molecules of hydrogen in the cylinder
= X

Explain Why?
"The number of atoms in a certain volume of hydrogen is twice the number of atoms in the same volume of helium at the same temperature and pressure."
The gases chlorine, nitrogen, ammonia and sulphur dioxide are collected under the same conditions of temperature and pressure. The following table gives the volumes of gases collected and the number of molecules (x) in 20 litres of nitrogen. You are to complete the table giving the number of molecules in the other gases in terms of x.
| Gas | Volume (in litres) | Number of molecules |
| Chlorine | 10 | x |
| Nitrogen | 20 | |
| Ammonia | 20 | |
| Sulphur dioxide | 5 |
