1. (MeOH-water) Do the numbers on the x-axis refer to mole fraction of methanol or mole fraction of water? 2. (MeOH-water) If a mixture of methanol and water is distilled to maximum theoretical separation, what will come out of the top of the distillation column?
3. (C3H5OH-water) Suppose you mix 4.0 moles of water with 1.0 mole of propanol at room temperature, then heat it. What will be the composition (mole fraction) in the first vapor?
4. (C3H5OH-water) If a mixture of methanol and water is distilled to maximum theoretical separation, what will come out of the top of the distillation column?
5. (3 pts) If you have an initial liquid with a mole fraction of methanol of 0.1, how many theoretical plates are necessary to prepare a mixture which is at least 80% (mole percent) of MeOH?
6. (3 pts) If you have an initial liquid with a mole fraction of C3H5OH of 0.1, how many theoretical plates are necessary to prepare a mixture which is at least 50% (mole percent) of C3H5OH?
