The table above shows the % compositions of the vapor and liquid phases at equilibrium for solutions of A and B at the indicated temperatures:

1). A mixture of 30g of A and 70g of B is distilled using a dimple distillation apparatus. At what temperature would the first drop distill?

2). A misture of 50g of A and 50g of B is distilled usinga very efficient fractionating column. Construct a distillation curve (temperature vs. mL of distillate) for this system knowing that the density of A and B is 1.05g/mL and 0.96g/mL, respectively.
