Gas binary system vinyl chloride - water

[bigufo]

hello,
how I can calculate the composition of a gas binary mixture of vinyl chloride and water knowing that I have only the following informations:

• the water is saturated by the vinyl chloride
• the pressure of the mixture is 4bars

or can you tell me what I have to look as information to be able to calculate the concentration of the water in the mixture?

thank you
