According to the ideal gas law, a 10.59 mol sample of argon gas in a 0.8229 L container at 495.4 K should exert a pressure of 523.2 atm. By what percent does the pressure calculated using the van der Waals' equation differ from the ideal pressure? For Ar gas, a = 1.345 L2atm/mol2 and b = 3.219×10-2 L/mol.

??? %



Hint: % difference = 100 × (P ideal - Pvan der Waals) / P ideal
