The critical volume of a gas is 0.072 lit. `"mol"^(-1)`.The radius of the molecule will be, in cm

A

`(3/(4pi)xx10^(-23))^(1/3)`

B

`((4pi)/3xx10^(-23))^(1/3)`

C

`((3pi)/4xx10^(-23))^(1/3)`

D

`(3/(4pi)xx10^(-8))^(1/3)`

Text Solution

Verified by Experts

The correct Answer is:
A
`b=16/3 pir^3 N_A , V_c=3b implies 0.072xx1000=16/3xx6.023xx10^23xxpir^3xx3`
