Use these diagrams to answer the following questions. a) Estimate the bubble point temperature and the equilibrium vapor composition | associated with a 20 mole% methanol-80 mole% water liquid mixture at 1 atm. b) Estimate the boiling points of pure methanol and water at 1 atm. c) A closed cylinder contains 100 moles of a liquid mixture comprising 35 mole% methanol and 65 mole% water at 40C and 225 mm Hg. What are the liquid and vapor compositions in equilibrium with each other at 40C and 112.5 mm Hg? Also calculate the number of moles of vapor (nv) and liquid (n) in equilibrium at 40C and 112.5 mm Hg.
