25. a) A solution is made by mixing 28.0g of chloroform (CHCl3) in 175.0g of benzene (CHH6). Determine the freezing point of the solution, if the freezing point of pure benzene is 5.50C. The K r value of benzene is 5.12C/m. b) Instead of chloroform, aluminum fluoride was added to generate the same concentration of solution. Assuming that this salt dissolves in benzene, what would the freezing point of the solution be
