Txy diagram problem

  1. Dec 3, 2016 #1
    Hi Everyone,
    I am having trouble grasping the concept of Raoult's law, partial pressures etc. One problem in specific is: A system contains 3 moles of methanol and 7 moles of water at 25 degrees celsius. The temperature is raised until there is 40 mol% methanol in the gas phase. How much is left in the liquid phase?
    The Txy diagram is attached.
    Thanks so much guys,
