is there a chart available that show the vapor pressure of Isopropyl alcohol and water solutions at 68 degrees F ?

Answer 1

I doubt it. It would vary according to the concentration (Roults law). What will be avaialbe is the vp of water vs temp, and the vp of alcohol vs temp, and then you use Roults law adding the vapor pressures according to the mole fractions of the alcohol and water in the solution.
