Aniline (MW 93) co-distills with water at 98.2. The partial vapor pressure of water at 98.2 is
  712 mm Hg. You need to isolate 10 g of aniline. What is the minimum amount of water it will
  take to steam-distill this amount of aniline?



Question 2

At 99.6, water has a vapor pressure of 750 mm Hg and quinoline (immiscible with water) has
  a vapor pressure of 10 mm Hg. What weight of water must be distilled for each gram of quin
  oline in a steam distillation at 760 mm Hg?

Answer to Question 1

wtwater/10 g = (712 x 18)/(48 x 93) = 28.7 g

Answer to Question 2

wtA = 1.0 x (750/10) x (18/129.17) = 10.4 g
