Chapter 11, Problem 51QP

Interpretation Introduction

Interpretation:

The amount of $\text{KI}$ required to prepare $700\text{g}$ of a solution having $15.0\%\text{KI}$ by mass is to be determined.

Concept Introduction:

$\text{KI}$ is an ionic compound and water is a polar solvent. Thus, $\text{KI}$ is easily soluble in water to give the solution by ion-dipole force between them. The percent-by-mass is calculated by dividing the solute mass by the mass of solution and multiplied by $100\%$ .
