The diameter of oxygen molecule is 2.94x...

The diameter of oxygen molecule is `2.94xx10^(-10)m`. The Vander Waal's gas constant 'b' in `m^3//mol` will be

A

3.2

B

16

C

`32xx10^(-4)`

D

`32xx10^(-6)`

Text Solution

Verified by Experts

The correct Answer is:
D
`b=4xx" total volume of all the molecules "`
`=4xxNxx4/3pi(d/2)^3=2/3piuNd^3`
`=2/3xx3.14xx6.02xx10^(23)xx(2.94xx10^(-10))^3`
`=32xx10^(-6)m^3//mol`
