Calculate the pressure exerted by Ar for a molar volume of 1.42L mol-1 at 300.0 K using the van der Waals equation of state. The van derWaals parameters a and b for Ar are 1.355 bar dm6 mol-2 and 0.0320 dm3 mol-1,respectively. Is the attractive or repulsive portion of the potential dominant under these conditions?
