Use the Antoine equation to calculate the saturation pressure
for acetone, and isopropanol at 328.15 K. Circle and label these points on
the plot above at the mole fractions which indicate pure acetone and pure
isopropanol respectively. (Isopropanol, which is also called 2-propanol is not in the textbook's
Appendix. You may use Antoine parameters A=9.976, B=2521.524, and C=-102.409.)
