State: Avogadro's law
Define atomicity of a gas.
A vessel contains N molecules of oxygen at a certain temperature and pressure. How many molecules of sulphur dioxide can the vessel accommodate at the same temperature and pressure?
Solve the following:
A vessel contains X number of molecules of hydrogen gas at a certain temperature and pressure. How many molecules of nitrogen gas would be present in the same vessel under the same conditions of temperature and pressure?
State : Avogadro's law
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 |
What are the main applications of Avogadro's Law?
Samples of the gases O2, N2, CO2 and CO under the same conditions of temperature and pressure contain the same number of molecules x. The molecules of oxygen occupy V litres and have a mass of 8 g under the same conditions of temperature and pressure.
What is the volume occupied by:
- x molecules of N2,
- 3x molecules of CO,
- What is the mass of CO2 in grams?
- In answering the above questions, which law have you used?
State the atomicity of Sulphur.
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.
