What is boiling point of a decimolal aqueous solution of glucose if molal elevation constant for water is 0.52^ C kg mol ⁻¹ ?

Options

  1. A101.52^ C
  2. B99.95^ C
  3. C99.48^ C
  4. D100.052^ C

Correct answer

D. 100.052^ C

Step-by-step solution

aligned & T _ b = k _ b m & T _ b =0.52 0.1, ~m =0.1 (decimolal solution) & =0.052^ C & T _ b = T _ b - T _ b ^ ( T _ b ^ = . Boiling point of pure water) & 0.052^ C = T _ b -100^ C & T _ b =100.052^ C aligned
