A natural product (MW = 150) distills with steam at a boiling temperature of 99?C at atmospheric pressure. The vapor pressure of water at 99? is 733 mmHg.
i) Calculate the weight of the natural product that co-distills with 1.00g of
water at 99?C.
ii) How much water must be removed by steam distillation to recover this natural
product from 0.5 g of a spice that contains 10% of the desired substance?
iii) What is the percent composition of the vapour produced during the steam distillation
