Final answer:
The freezing point of the solution is determined by subtracting the freezing point change from the pure solvent's freezing point. Given the freezing point change is 24.0°C, the new freezing point is -24.0°C, which is not among the provided answer choices.
Step-by-step explanation:
According to the given information, the normal freezing point of water is 0.0°C. The property we are discussing here is the freezing point depression, which is a colligative property. This property states that the presence of a solute lowers the freezing point of a solvent. Given that the freezing point decreases by 24.0°C, we can calculate the new freezing point of the solution.
The formula to determine the new freezing point of the solution is: Freezing Temperature = Pure Solvent's Freezing Point - Freezing Point Change Observed. Using this formula, we can determine the freezing point of the solution to be:
Freezing Temperature = 0.0°C - 24.0°C = -24.0°C
Therefore, none of the provided answer choices are correct. If these were the options presented by a test or a textbook, it would likely be an error, and the instructor should be notified.
