Question

Part A Predict the boiling point of a mixture made up of 0.70 mole fraction of A and 0.30 mole fraction of B Express your answer as an integer and include the appropriate units. The boiling point of a mixture of two volatile liquids depends on how much of each component is present. This graph shows the boiling temperature versus mole fraction composition. (Figure 1) Fractional distillation is a physical process used to separate the volatile components of a mixture. The process is accomplished by repeated vaporations of the solution, each followed by condensation of the vapor.
