Question:
If the elevation in boiling point of a solution of 10 g of solute (mol. wt. = 100) in 100 g of water is \( \Delta T_b \), the ebullioscopic constant of water is?
If the elevation in boiling point of a solution of 10 g of solute (mol. wt. = 100) in 100 g of water is \( \Delta T_b \), the ebullioscopic constant of water is?

The Correct Option is C
Solution and Explanation
The elevation in boiling point \( \Delta T_b \) is given by the formula:
\[
\Delta T_b = K_b \times \text{molality}
\]
Using the given data, the ebullioscopic constant \( K_b \) can be calculated.
