Isolatoin of Citral from Lemongrass Oil

1. Assume you have a solution containing two volatile liquids. Given the data for liquid A: MM = 56.89 g/mole, partial pressure = 0.903 atm and for liquid B: MM = 14.52 g/mole, partial pressure = 0.995 atm, what is the A:B ratio of the distillate?

2. Assume you recovered 0.291 mL of citral in this experiment. How many grams of lemon grass oil did you begin with if citral comprises 9.44% of the oil?

3. Assume the starting volume of lemon grass oil (density = 1.254 g/mL) you used was 2.87 mL and citral composed 23.1% of the lemon grass. How many grams of citral were present?
