Chapter 8, Problem 8.74QP

Interpretation Introduction

Interpretation: for the given reaction, the percent purity of ${\text{Fe}}_2{\text{O}}_3$ to be determined.

Concept introduction:

• Equation for Number of moles of a substance, from its given mass is,

$\text{Number of moles}\text{=}\frac{\text{Given}\text{mass}}{\text{Molecular}\text{mass}}$

• Percent yield of reaction is the ratio of mass of actual yield to the mass of theoretical yield and multiplied with hundred.
