6. For benzophenone, the freezing point constant, Kf, is 8.7°C kg mol-1 and its normal freez- ing point is 47.8°C. a) What is the freezing point of a solution containing 5.0 g of benzophenone and 0.5 mL of cylcohexone, C6H100? The density of cyclohexanone is 0.948 g/mL. b) How does the freezing point of the solution calculated in 6a compare to the freezing point that you determined in Part 2 of this experiment for the same solution (5.0 g of benzophenone and 0.5 mL of cylcohexone)? Explain what could have caused your experimental freezing point to be higher or lower than the freezing point calculated for the same solution in 6a.
