   Small known quantities of 1,1-dichloroethene vapor were added to a closed vessel containing a known amount of water and headspace. The equilibrium vapor pressure above the solution was monitored after each addition. At the equilibrium pressure,  the added to 1,1-dichloroethene was adjusted for the headspace volume, and the remainder was assumed to have dissolved in water.
