Drop in pressure, what volume is left?

  1. Oct 29, 2014 #1
    1. The problem statement, all variables and given/known data

    There is a vessel with 10 Liters of Liquid Nitrogen.
    The normal pressure is 100 Psi.
    After a couple hours the pressure is dropped to 47 Psi because of leak in the vessel.

    How much of the Liquid Nitrogen did we lose/is left in the vessel?
    2. Relevant equations

    I'm really not sure. I thought about P1V1 = P2V2, but I don't think that will work here.

    3. The attempt at a solution

    Using P1V1 = P2V2 I got an answer, but I think that will only work for a closed system (drop in pressure means increase in volume and vice versa)

    So, does anyone have an idea how to solve this?

    What is the exact wording of this problem (not your paraphrasing)? There seems to be information missing.
