The mass of `1` litre of helium under a pressure of `2 atm` and at a temperature of `27^(@)C` is

A

`0.16 g`

B

`0.32 g`

C

`0.48 g`

D

`0.65 g`

Text Solution

Verified by Experts

The correct Answer is:
B
`PV = nRT = (M)/(M_(0))RT`
`M`: mass of gas, `M_(0)`: molecular mass of gas
`R = 0.0821" litre atm"//"mole K"`
`M = (M_(0) PV)/(RT) = (4 xx 2 xx 1)/(0.0821 xx (27 + 273)) = 0.32 g`
