If the elevation in boiling point of  a solution of 10 g of solute (mol.wt=100) in 100 g of water is $\triangle T_{b}$ , the ebulliscopic constant of water is 

Answer:

Explanation:

 We know that, $\triangle T_{b}= \frac{1000 \times K_{b} \times w}{W \times M}$

$M= \frac{1000 \times K_{b} \times w}{W \times \triangle T_{b}}$

$\triangle T_{b}=\frac{1000 \times K_{b} \times 10}{100 \times 100}$

$\triangle T_{b}=K_{b}$
