What is the boiling point of 0.5 molal aqueous solution of sucrose is 0.1 molal aqueous solution of glucose boils at

Options

  1. A100.32^ C
  2. B100.80^ C
  3. C100.16^ C
  4. D100.62^ C

Correct answer

B. 100.80^ C

Step-by-step solution

aligned & T _ b = K _ b m & T _ b - T _ b ^ = K _ b m & T _ b -100^ C = K _ b 0.5 & 100.16-100^ C = K _ b 0.1 & . ~K _ b = 0.16 0.1 =1.6 (From equation 2 ) & T _ b -100^ C =1.6 0.5 & ~T _ b =100+0.80=100.80^ C aligned
