(P + a/V^2) (V - b) = RT
P is pressure, V is volume and T is temperature.
[P] = [F/A] = [MLT^−2/L^2] = [ML^−1T^−2]
[V] = [L^3]
We cannot add or subtract quantities of different dimensions. Therefore
[P] = [a/V^2] ⇒ [a] = [PV^2] = [ML^−1T®−2 L^6] = [M L^5 T^−2]
[a] = [M L^5 T^−2]
Similarly,
[b] = [V] = [L^3]
P is pressure, V is volume and T is temperature.
