Question

Use this information to answer the following questions- An octane (b.p. = 125.7 C)-water mixture has a boiling point of 89.6 C. and a % water composition of 25.5%. a) When a simple distillation is performed on a mixture containing 25. g water and 745 g octane, at what temperature will the entire distillation occur? b)When fractional distillation is performed on a mixture containing 25.5 g water and 84.5 g of octane, at what temperature will the first 100.0 g distill? At what temperature wt remaining 10.0 g distill? c) Make a sketch for octane-water similar to that shown for ethanoi-water minimum boiling point phase diagram below:
