According to the ideal gas law, a 1.042 mol sample of krypton gas in a 1.268 L container at 270.7 K should exert a pressure of 18.25 atm. By what percent does the pressure calculated using the van der Waals' equation differ from the ideal pressure? For Kr gas, a = 2.318 L2atm/mol2 and b = 3.978×10-2 L/mol.
__________ %
Hint: % difference = 100×(P ideal - Pvan der Waals) / P ideal
