What is the freezing point of a 3.00 m aqueous solution of a nonvolatile nonelectrolyte? (The freezing point depression for water is 1.86^° C/m) A)-3.00^° C B)-5.58^° C C)3.00^° C D)5.58^° C

Using the formula ∆T = Kf × m, where Kf is the freezing point depression constant for water and m is the molality of the solution, we can calculate the freezing point depression for the given solution: ∆T = (1.86 °C/m) × 3.00 m = 5.58 °C. Since the freezing point depression is negative, the freezing point of the solution is lower than the freezing point of pure water. Therefore, the freezing point of the solution is: 0 °C - 5.58 °C = -5.58 °C. The best choice is B, which is the only one that matches this value.
