Chapter 7, Problem 7.68E

Interpretation Introduction

(a)

Interpretation:

The osmolarity for a $0.15\text{M}$ solution of glycerol, a nonelectrolyte is to be calculated.

Concept introduction:

Solutes which give conducting solutions on dissolution are called electrolytes. Those which dissociate completely in the solution are known as strong electrolytes. Solutes which do not give conducting solutions are called nonelectrolytes. The properties which depend on the number of solute particles are known as colligative properties. Some of these properties are boiling point, freezing point and osmotic pressure.

Interpretation Introduction

(b)

Interpretation:

The osmolarity for a $0.15\text{M}$ solution of ${\left({\text{NH}}_{\text{4}}\right)}_{\text{2}}{\text{SO}}_{\text{4}}$, a strong electrolyte is to be calculated.

Concept introduction:

Solutes which give conducting solutions on dissolution are called electrolytes. Those which dissociate completely in the solution are known as strong electrolytes.

Interpretation Introduction

(c)

Interpretation:

The osmolarity for a solution containing $25.3\text{g}$ of $\text{LiCl}$ (a strong electrolyte) per liter is to be calculated.
