The van der waal's gas equation is `(P+a/V^(2))(V-b)=RT`, where P is pressure, V is molar volume and T is the temperature of the given sample of gas. R is called molar gas constant, a and b are called van der waal's constants.
The dimensional formula for b is same as that for

Options

A. P
B. V
C. `PV^(2)`
D. RT

Answer

B

Explanation

`[b]=[V]`
