Question 3 (2 points) A liquid mixture of 0.39 mole fraction benzene and the rest styrene at 74.3C is in equilibrium with vapours of the two components. Determine the mole fraction of benzene in the vapour. Your answer must have three decimal figures and should be accurate to +0.002. Do not truncate intermediate results, but only the final answer. Your Answer: Answer Hide hint for Question 3 Use the following Raoult's Law equations to solve for the unknown: X1P1* = y1PT.
