The refractive index of pure cyclohexane is 1.4264 and that of pure toluene is 1.4967. During the distillation three fractions were collected. In each case the middle fraction was discarded. For the simple distillation the refractive index of the first fraction is 1.4475 and that of the final fraction is 1.4891. For the fractional distillation the refractive index of the first fraction is 1.4302 and that of the final fraction is 1.4938. Use this data to calculate the percent composition of the four fractions (two from each distillation).
