How to Calculate CO2 Saturation Levels in Saline Water?

[uri segal]

i am studying a system of dissolved CO2. it is in oversaturation, and NOT in equilibrium. but i don't know how to express its saturation level. all i know is the molar fraction of CO2 that escapes after reaching equilibrium. how can i calculate that?

The same way you'd calculate anything else; composition of starting mixture/solution minus composition of "equilibrium" mixture.
