Chapter 14, Problem 44PE

Interpretation Introduction

Interpretation:

Molar mass of compound if dissolution of $4.80\text{ g}$ in $22.0\text{ g}$ of ${\text{H}}_{\text{2}}\text{O}$ gives solution that freezes at $-2.50°\text{C}$ has to be determined.

Concept Introduction:

Colligative properties are dependent on amount of solute and not on their natures. These are caused due to addition of nonvolatile solute in any solution. Below mentioned are colligative properties.

1. Freezing point depression

2. Boiling point elevation

3. Vapor pressure lowering

4. Osmotic pressure
