1.) Estimate the molar volume of CO2 at 400 K and 125 atm by treating it as a Van der Waals gas. 2.) Cylinders of compressed gas are typically filled to a pressure of 200 bar.  For oxygen, what would be the molar volume at this pressure and 250C based on: a) the perfect gas law; b) the van der Waals equation. For oxygen, a = 1.364 atm2L2/mol2 and b = 3.19x10-2 L/mol.
