# Problem: Calculate the pressure of a 2.975-mol sample of N2 in a 0.7500-L flask at 300.0 oC using the van der Waals equation and then repeat the calculation using the ideal-gas equation. Within the limits of the significant figures justified by these parameters, will the ideal-gas equation overestimate or underestimate the pressure, and if so by how much? For N2, a = 1.39 L2atm/mol2 and b = 0.0391 L/mol.
