Calculation of volume after phase change

  1. Aug 5, 2014 #1

    It's been a while since I've done calculations like this so I was wondering if someone can help me calculate the volume of a gas at a specific temperature as compared to its liquid volume when measured below its boiling point. I can't seem to find a phase diagram for this material, is there a way to calculate it?

    Assume that the gas is ideal, and use the ideal gas law ##PV = N k_\mathrm{B} T## (or ##PV = n R T##) to find the volume. To know ##N## (##n##), you can use the volume of the liquid and its density.
