Chapter 16, Problem 125E

Interpretation Introduction

Interpretation:

The molar mass of the solute, if a solution of $\text{16}\text{.1}\text{g}$ of an unknown solute in $\text{6}{\text{.00×10}}^{\text{2}}\text{g}$ of water boils at $\text{100}\text{.28}°\text{C}$ is to be calculated.

Concept introduction:

Molality is defined as the measure of concentration of moles of solute in a solution. It is calculated by dividing the no. of moles of solute by the weight of solvent in $\text{Kg}$.

Colligative properties are defined as the physical properties of some dilute solutions which depend on the molal concentration of the solutes.
