An ideal solution is created by mixing A and B in the molar ratio 2:3. The mixture has a normal boiling point at 85 degrees Celsius.

A. Given that the vapor pressure above pure A at 85 degrees Celsius is 0.79 atm, what is the vapor pressure (in atm) of A above the mixture?

B. What is the vapor pressure of B above the mixture?

C. What would be the vapor pressure above pure B at 85 degrees Celsius?

D. Predict the normal boiling point of pure B (in degrees Celcius) given that deltaHvaporization(Pure B)=67.9kJ/mol.
