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

0.64 g

Text Solution

Verified by Experts

The correct Answer is:
b
`"No. of moles (n)"=(PV)/(RT)=(2xx10^(5)xx10^(-3))/(8.3xx300)=0.08`
`"Mass of one of He"=4g`
`"Mass of n moles "=(nxx4)=(0.08xx4)=0.32g`
