The density of N2(g) is 0.824g cm^-3 at 3000 bar and 273.2K
1. Determine the average distance separating the centers of the N2 molecules (assumed spherical; cubic closest packing) in this fluid.
2. How can compare this distance to the molecular diameter of the molecule measured by the van der walls coefficient, b. For N2, a=1.370 bar L^2 mol^-2, and b = 3.87*10^-2 L mol^-1
