Question

i need help with question 3, thank u

6 Recoveng of eigenel isolalea hyat Rtan purified by' simple distillation? x too% 2 Why is eugenol steam-distilled rather noleuar we 3 A natural product (MW 164.00 a/mole) distils with steam at a boiling temperature of 98.0 °C at atmospheric pressure. The vapour pressu re of water at 98.0 °C is 731.0 mmHg a. Calculate the mass of the natural product that co-distils with 1.00 g of water at 98.0 °C b. What volume of water must be removed by steam distillation to recover this natural product from 0.500 g of a spice that contains 10.0% of the desired substance? c. Calculate the mass percent composition of the vapour produced during the steam distillation. The steam distillation of cloves is comparable to that of the above spice. Why does so much more water need to be distilled for complete removal of eugenol than what is calculated above? 5. A mixture of para-nitrophenol and ortho-nitrophenol can be separated by steam distillation. The o-nitrophenol is steam volatile, while the p-nitrophenol is not volatile. Explain. Base
