If the elevation in boiling point of a solution of 10 ~g of solute ( mol . wt =100) in 100 ~g of water is T b , the ebullioscopic constant of water is

Options

  1. AT_ b 10
  2. BT_ b
  3. C10 T_ b
  4. D100 T_ b

Correct answer

B. T_ b

Step-by-step solution

m = 1000 k _ b w W T_ b or aligned k_ b &= m W T_ b 1000 w = 100 100 T_ b 1000 10 &= T_ b aligned
