In the van der Waals equation?

Question

In the van der Waals equation


"R" is the gas constant (0.0820574 L atm mol-1K-1) and "V" is the volume in litres of "n" moles of gas at the temperature "T" in Kelvin; "a" and "b" are constants which are dependent upon the gas. Calculate the pressure, P, for 2.36 moles of argon for which a is 1.34 L2 atm mol-2 and b is 0.0322 L mol-1 if it is contained in a 3.24 L container at 322 K.

Answer 1

Van der Waal's equation is given here:
