For a van der waals gas, `b=5.0xx10^(-2)L*mol^(-1)`. What is the diameter of a molecule of this gas?

Text Solution

Verified by Experts

`b=4N_(A)xx(4)/(3)pir^(3)`
`5xx10^(-2)xx1000cm^(3)*mol^(-1)=4xx6.023xx10^(23)xx(4)/(3)pir^(3)`
or, r=1.705`xx10^(-8)cm`
`therefore`Diameter of a molecule=`3.41xx10^(-8)cm`
