Calculate the difference in pressure of 10.00g of carbon dioxide confined to a container of volume 100cm3 at 25.0 C between treating it as a perfect gas and a van der Waals gas. Compute the answer in the form of the ratio: (pVdW-pIG)/pIG , where "IG" stands for ideal gas and "VdW" for van der Waals.
