Question

. A gas cylinder of capacity 20 litre is filled with gas X the mass of which is 10g. The same cylinder is filled with hydrogen gas at the same temperature and pressure the mass of the hydrogen gas is 2g: (a) What is the vapour density of the gas X? (b) What is the molecular mass of the gas X?​

Answer 1

Explanation:

A gas cylinder of capacity of 20 dm3 filled with gas X the mass of which is 10 g. 'when the same cylinder is filled with hydrogen gas at the same temperature and pressure the mass of the hydrogen is 2 g, hence the relative molecular mass of the gas is: 5. 10.
