Under identical conditions, separate samples of O2 and an
unknown gas were allowed to effuse through identical membranes
simultaneously. After a certain amount of time, it was found that
6.36 mL of O2 had passed through the membrane, but only 3.93 mL of
of the unknown gas had passed through.

Problem Statement: Determine the pressure exerted by 3.00 mol of Ar gas having a volume of 50.0 L at 25.0ºC (298.2 K) using both the ideal gas law and van der Waals equations. Which is larger—the pressure determined using the ideal gas law or the van der Waals equation?

1. Use the ideal gas law to determine the pressure exerted by 3.00 mol of Ar gas with a volume of 50.0 L at 25.0ºC (298.2 K).
2. Using the van der Waals equation, determine the pressure exerted by 3.00 mol of Ar gas with a volume of 50.0 L at 25.0ºC (298.2 K).
