(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A container having a volume of 40 L contains one of the following fluids att the given initial conditions. After a leak, the temperature and pressure are remeasured. For each option, determine the kilograms of fluid lost due to the leak, using Peng_robinson equation.

methane T(initial) = 300 K, P(initial) = 100 bar T(final) = 300 K, P(final) = 50 bars

2. Relevant equations

The Peng robinson equation of state is written as:

Z = [tex]\frac{1}{1-bp}[/tex] - [tex]\frac{a}{bRT}\frac{bp}{1+2bp - b^{2}*p^{2}}[/tex]

3. The attempt at a solution

I know how to solve for a and b. If you find it necessary for me to show you this, i can. But I don't see the purpose. However p, which stands for molar density (n/V), I do not understand. Considering the whole point is to find the amount of moles lost, I can't see how this can be solved unless I know the moles in the tank.
