100 mL of any gas weighs 0.144g at STP. What is the vapour density of the gas?

Text Solution

Verified by Experts

Mass of 100 mL of the gas at STP=0.144g
`therefore22400mL` of the gas at STP weighs`=(0.144xx22400)/(100)`
=32.256g
Hence, molecular mass of the gas=32.256g
`therefore`Vapour density of the gas`=("molecular mass")/(2)`
`=(32.256)/(2)=16.128`
