Name the law om which same conditions of temperature and pressure
Samples of the gases O2, N2, CO2 and CO under the same conditions of temperature and pressure contain the same number of molecules represented by X. The molecules of Oxygen, occupy V litres and have a mass of 8 g. Under the same conditions of temperature and pressure:
In answering the above questions, which law have you used?
State Avogadro's Law
Differentiate between N2 and 2N.
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."
You have collected
- 2 litres of CO2
- 3 litres of chlorine
- 5 litres of hydrogen
- 4 litres of nitrogen and
- 1 litre of SO2,
under similar conditions of temperature and pressure. Which gas sample will have the greatest number of molecules? Justify your answer.
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 |
