[SOLVED] Physical chemistry problem

Homework Statement


A closed vessel of 5L volume is kept at 80 degrees celcius and contains a mixture of two liquids A and B dissolved in a solvent, with their initial concentrations [A]=0.1mol/L and =1.0mol/L. The volume of the gas phase is 2L and it initially contains only nitrogen.

Liquids A and B react as follows

A+B <--> C+D

where D is water. It is known the reaction reaches 80% conversion, all liquid components are miscible and only water is volatile.

If the partial pressure of water in the vessel at the end of the reaction is 0.1 bar, calculate the amount of solvent used in moles.

Note: You may need to use the Antoine equation.
