If 3.21 moles of ammonia gas occupy 5.22 L at 50.0oC, calculate the pressure of the gas using the ideal gas equation AND by using the van der Waals equation. Compare each value to the actual measured pressure of 15.4 atm under these conditions.
R = 0.0821 L atm K-1 mol-1, for ammonia under these conditions,
a = 4.17 atm L2 mol-2 and b =0.0371 L mol-1.
