Options
- A. 1 1 K kg mol ^ -1
- B. 1 6 K kg mol ^ -1
- C. 2 2 K kg mol ^ -1
- D. 2 6 K kg mol ^ -1
Answer
B. 1 6 K kg mol ^ -1
Step-by-step solution
The depression in freezing point is given by the formula: T_f = i K_f m For a nonelectrolyte, the van't Hoff factor i = 1. Substituting the given values: 0 48 = 1 K_f 0 3 K_f = 0 48 0 3 = 1 6 K kg mol ^ -1 Answer: 1 6 K kg mol ^ -1
