Liquid Nitrogen comes in large cylinders that require special tank carts and hold 120L of liquid at 77K. Given the density of liquid nitrogen of 0.840g/cm3, use the van der Waals equation to estimate the volume of nitrogen of the nitrogen gas after it evaporates at 77K. (hint: because V shows up in 2 places in the van der waals equation, you will have to do an iteration procedure to estimate V. neglect th an2/V2 term initially and calculate V; then substitutue this into the an2/V2 term, evaluate the pressure term, resolve for V, and repeat until the number doesn't change.
