I tried to figure out using the boiling point elevation formula. I also tried graphing the points to see what I could find. But i am confused of what is the right thing to do.
I would do this.
Use the Clausius-Clapeyron equation. You have T and P at several points. That will allow you to calculate delta Hvap. I might do two or three of the points and take an average. After knowing delta Hvap, one other T/P point can be added. The boiling point will be the T at which P is 760 torr.
