Question
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.
Solution
According to Avogadro's law, equal volumes of gases contain equal no. of molecules under similar conditions of temperature and pressure. This means more volume will contain more molecules and least volume will contain least molecules.
So, 5 litres of hydrogen has the greatest no. of molecules with the maximum volume.
