Question

Density of a gas at STP is 1.2 gram per litre . Calculate vapour density of the gas .​

Answer 1

Answer:

we know at STP any gas occupies 22.4l at pressure 1atm

and temperature 273K

density = mass/ volume

1.2 = mass/ 22.4

mass = 26.88g

we know that molecular mass = 2× vapour density

=> vapour density = molecular mass / 2 = 26.88/2

= 13.44

Answer 2

Answer:

The volume occupied by 11.2 g of the gas at STP will be. ∵22.4g of gas occupies 22.4L at S.T.P.31

A gas has Vapour density equal to 11.2 the volume occupied by 1 g of the gas at STP will be
