The elevation in boiling point of 2.25 mole aqueous solution of a substance is K b = 0.52 K k g m o l - 1

Options

  1. A0.5 K
  2. B0.50 K
  3. C0.13 K
  4. D2.08 K

Correct answer

C. 0.13 K

Step-by-step solution

Key Idea Elevation in boiling is directly proportional to molal concentration of solute in a solution Δ t 2 ∝ Δ T b = K b m The elevation in boiling point Δ T b of 0.25 molal aqueous solution of a substance is Δ T b = K b × m = 0.52 × 0.25 = 0.13 K
