The elevation in boiling point of a solution of 10 ~g of a binary electrolyte (of molecular mass 100) in 100 ~g of water is T_b . Then, the value of K_b for water is

Options

  1. AT_b 2
  2. B10
  3. C10 T_b
  4. DT_b 10

Correct answer

A. T_b 2

Step-by-step solution

Weight of solute =10 ~g Weight of solvent =100 ~g Molecular mass of electrolyte =100 aligned T_b & =i K_b wt. of solute molecular mass 1000 wt. of solvent & =2 K_b 10 100 1000 100 aligned aligned T_b & =2 K_b K_b & = T_b 2 aligned
