1. A 75-mole mixture that is 40.0 mol% ethanol at 70 °C is cooled at constant pressure. At
what temperature will the first liquid bubble form from this mixture?
2. The mixture in (1) is further cooled to 63 °C. What is the condition of the solution at this
temperature? What is the amount and composition of the liquid and/or vapor phases
formed from the mixture at this temperature?
3. At what temperature will the last drop of vapor from the mixture condense?
Note: Use a tolerance value of 1 x 10-² in calculations. Do it manually.
