The ηD20 value for cyclohexane is 1.4266 while the ηD20 value for toluene is 1.4961 . Thus, your refractive indices should be between these two values. The mole fractions Xof eachrof yo samples can be computed using the equations: 1.4266 Xcyclohexane + 1.4961 Xtoluene ësample and X + Xtolucne cyclohexane msample is the measured refractive index of sample A, B, or C. Solving the above equations for the mole fraction of cyclohexane gives: Xcyclohexane 14961-sample 0.0695 The mole fraction of toluene is 1-Xayclohexane and the percentages are the mole fraction times 100. For example, if ηD20 for your sample were 1.4432, the sample is 76% cyclohexane and 24% toluene. For the Conclusions Section: Report the boiling point of Make a table showing the n" 2o values and percentages of cyclohexane and toluene in each of the fractions. Make a graph of temperature (y axis) vs. volume (x axis) for the distillation. The volume will start at 0 mL. There will be one graph for the entire distillation; i.e., after plotting temperature vs. volume for fraction A, the volume collected in fraction B will follow that of A and fraction C will follow so that the volume is the total volume collected during distillation. The graph must be computer generated. Connect the dots rather than making a best fit line cyclohexane.
