Calculate the cryoscopic constant of a solvent if depression in freezing point of 0 3 m solution of nonelectrolyte is 0 48 K

Options

  1. A1 1 K kg mol ⁻¹
  2. B1 6 K kg mol ⁻¹
  3. C2 2 K kg mol ⁻¹
  4. D2 6 K kg mol ⁻¹

Correct 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
