![## Freezing Point Depression of Sugar Solution
A student prepared a sugar solution containing 1.3658 g of sugar (C₁₂H₂₂O₁₁) in 25.00 mL of water and produced the following freezing point curves. The task is to determine the \( K_f \) of water based on the student's data.
### Graphs and Analysis
#### 1. **Freezing Point of Pure Water**
- **Axes**: The x-axis represents time (seconds), ranging from 0 to 220 seconds. The y-axis represents temperature (°C), ranging from -5 to 25 °C.
- **Curve**: The curve shows the cooling of pure water over time. Initially, the temperature decreases rapidly until it stabilizes at around 0°C.
#### 2. **Freezing Point of Sugar Solution**
- **Axes**: Similar to the first graph, the x-axis represents time (seconds) and the y-axis represents temperature (°C).
- **Curve**: The cooling curve of the sugar solution indicates a gradual decrease in temperature, stabilizing at a lower point than that of pure water.
### Question
Based on the data, what is the \( K_f \) of water?
#### Options:
A. 230 °C/m
B. 1.8 °C/m
C. 0.041 °C/m
D. 24 °C/m
Students are to analyze the graphs and select the appropriate \( K_f \) value using the freezing point depression concept.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3ac3995c-903b-421c-80b6-6f6642a05fa9%2F2573da20-8f69-4da0-8e62-5d140ce5e6d5%2Fcpai12gp_processed.png&w=3840&q=75)
