According to the ideal gas law, a 0.9921 mol sample of nitrogen gas in a 1.981 L container at 270.7 K should exert a pressure of 11.12 atm. By what percent does the pressure calculated using the van der Waals’ equation differ from the ideal pressure? For N₂ gas, a = 1.390 L²atm/mol² and b = 3.910E-2 L/mol.

 % 

Hint: % difference = 100 x (P _ideal – P_{van der Waals}) / P _ideal
