miketsap is on a distinguished road

I have a piston and inside there is a mixture(liquid A & B) of a compressible liquid.
In the pistons there is a hole but ONLY the liquid A can flow through. As a result the density of mixture in liquid A is getting lower.

Also I have the mixture density as an equation of PressureA and PressureB.

Do you know how I can define the density as percentage of A and B?

I need the percentage of liquid A and Liquid B in the volume each time so Density= 0.3PressureA + 0.7 pressureB if it's 30%LiqA and 70%liqB.

Please help me, thank you
