Give the deimension of R from PV = RT.

For real gases van der Waals equation of state can be expressed as (p+(a)/(V^(2)))(V-b)=RT where p is the pressure V is the molar volume and T is the absolute temperature of the given sample of gas and a,b, and R are constants. Which of the following does not have the same dimension as that of RT?

Find the dimension of the constant b in the van der Waals equation (p+a/V^2)(V-b)=RT .

Find the dimension of the constant a in the van der Waals equation (p+a/V^2)(V-b)=RT .

A gas obeys the equation of state P(V-b) = RT (The parameter b is a constant). The slope for an isochore will be :
