Use the References to access important values if needed for this question. According to the ideal gas law, a 9.845 mol sample of xenon gas in a 0.8342 L container at 500.6 K should exert a pressure of 484.8 atm. What is the percent difference between the pressure calculated using the van der Waals' equation and the ideal pressure? For Xe gas, a -4.194 L'atm/mol and b- 5.105x10-2 L/mol.
