A certain quantity of gas occupies 960 litre when collected over water at

300 \text{ K}

and

760 \text{ mm}

pressure. However the same quantity of dry gas occupies 608 litre at 2 atm and

400 \text{ K}

. The number of water vapours present in wet gas is (

R = 0.08 \text{ litre atm K}^{-1} \text{ mol}^{-1}

) .....
