IS es I needed for this question. 1 pts 2req 1 pts 2reg According to the ideal gas law, a 1.021 mol sample of argon gas in a 1.286 L container at 269.9 K should exert a pressure of 17.58 atm. What is the percent difference between the pressure calculated using the van der Waals' equation and the ideal pressure? For Ar gas, a = 1.345 L'atm/mol and b = 3.219x10-2 L/mol.
