I need help with this question, please!

The freezing point of benzene, CH, is 5.50C at 1 atmosphere. A nonvolatile, nonelectrolyte that dissolves in benzene is cholesterol. A student dissolves 12.40 grams of cholesterol, C27H460 (386.6 g/mol), in 217.2 grams of benzene. Use the table of boiling and freezing point constants to answer the questions below. Solvent Formula Ko (C/m) K (C/m) Water H20 0.512 1.86 Ethanol CH3CH2OH 1.22 1.99 Chloroform CHCl3 3.67 Benzene 66 2.53 5.12 Diethyl ether CH3CH2OCH2CH3 2.02 The molality of the solution is m. The freezing point of the solution is C
