In answering the above questions, which law have you used?
Differentiate between N2 and 2N.
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.
