The equation of state for a real gas such as hydrogen, oxygen, etc. is called the Van der Waal's equation which reads
`(P+(a)/(V^(2)))(V-b)=nRT`,
where a and b are constants of the gas. The dimensional formula of constant a is :

A

`"M L"^(5)"T"^(-2)`

B

`"M L"^(5)"T"^(-1)`

C

`"M L"^(-1)"T"^(-1)`

D

a being a constant, is dimensionless
