x, y (Chloroform), mol.frac.
1. A 300 mole mixture that is 30.0 mol% acetic acid at 0.4 bar is compressed isothermally.
At what pressure will the first vapor bubble form from this mixture?
2. The mixture in (1) is further compressed to 1.2 bar. What is the amount and composition
of the liquid and/or vapor phases formed from the mixture at this pressure?
3. At what pressure will the last drop of liquid from the mixture vaporize?
Note: Use a tolerance value of 1 x 10-² in calculations. Do it manually.
