Chapter 16, Problem 96A

Interpretation Introduction

Interpretation:

To state what information is required to calculate the boiling point elevation of a solution of hexane in benzene.

Concept introduction:

The boiling point elevation can be defined as the difference in the temperature between the boiling point of the solution and the boiling point of the solvent.

The boiling point elevationis given as $\Delta T_b=K_{b}m$

Answer to Problem 96A

In order to determinetheboiling point elevationof a solution of hexane in benzene we need to know the value of m and $K_b$

Explanation of Solution

The boiling point elevation can be calculated by taking help of the formula,

$\Delta T_b=K_{b}m$

Here, $\Delta T_b$ is the elevation in boiling point, $K_b$ is the molal boiling point constant and it depends on the solvent used, and m is the molality.

Therefore, we need to know the value of m and $K_b$ to calculate the boiling point elevation of hexane in benzene.

Conclusion

We need the information about the value of m and $K_b$ to calculate the boiling point elevation of hexane in benzene.
