1) Cyclohexane has a freezing point of 6.50 C and a K_f of 20.0 C/m. What is the freezing point of a solution made by dissolving 0.925 g of biphenyl (C_12H_10) in 25.0 g of cyclohexane?
2) Paradichlorobenzene, C_6H_4Cl_2, is a component of mothballs. A solution of 2.00 g in 22.5 g of cyclohexane boils at 82.39C. The boiling point of pure cyclohexane is 80.70 C. Calculate K_b for cyclohexane.
