Suppose you have a liquid solution containing two components, hexane and toluene. The boiling point of pure hexane is 69 C and the boiling point of pure toluene is 111 C. Your solution has a mole fraction of component hexane equal to 0.15, and the solution behaves as an ideal solution. What is the boiling point of this solution
