Suppose you have been given the task of distilling a mixture of hexane + toluene. Pure hexane has a refractive index of 1.375 and pure toluene has a refactive index of 1.497. You collect a distillate sample which has a refractive index of 1.441. Assuming that the refractive index of the hexane + toluene mixture varies linearly with mole fraction, what is the mole fraction of hexane in your sample?

3. You have been given the task of purifying a 60 mL sample of
toluene. In order to develop your plan of action, you ask about the
impurities likely to be present in the sample. You are told that it
contains small amounts of acetone (~10%). a Which technique would
you choose for the purification process? Why? (1 point) b. Clearly
describe the procedure you would use. (3 points) c. What simple
chemical test, performed with the original sample and...

You are fractionally distilling 100 mL of a 1:1 solution of
cyclohexane and toluene. After 2 mL has distilled you collect a
sample for analysis. It is determined that your sample contains a
mixture that is 92:8 cyclohexane/toluene. Calculate the number of
theoretical plates if the relative volatility (?) of the original
solution is 2.33
