Question
![**Problem Statement:**
Calculate the freezing point of a solution of 64.3 g of an ionic compound (FW = 136, i = 1.25) dissolved in 557 g of an organic solvent (FW = 96.22). The \( K_f \) of the solvent is 4.55 °C/m. The normal freezing point of the solvent is 11.1 °C. Report your answer to 1 decimal place.
**Details for Solution:**
1. **Molar Mass (FW) and Van't Hoff Factor (i):**
- Ionic Compound: FW = 136, i = 1.25
- Organic Solvent: FW = 96.22
2. **Mass of Compounds:**
- Ionic Compound: 64.3 g
- Organic Solvent: 557 g
3. **Freezing Point Depression Constant (\( K_f \)):**
- \( K_f \) = 4.55 °C/m
4. **Normal Freezing Point of Solvent:**
- \( T_f^{\text{solvent}} \) = 11.1 °C
5. **Required Calculation:**
- Determine the freezing point of the solution.
