```							Vander Waal's Universal equation for a non ideal gas :  ( P + a/v² ) * (V - b) = n R T with the symbols having the given meanings. P = pressure. V = volume. R = Universal Gas constant. T = absolute temperature. n = number of moles of the gas. Since P has dimensions of Force/Area, a/V² also will have the same units and dimensions. P = [ M ] [ L⁻¹ ] [ T⁻² ] = a / V² = a [ L³ ]⁻² So constant a = [ M ] [ L⁵ ] [ T⁻² ] Since b has same units and dimensions as that of V,   b = [ L³ ] Hope it helps
