Chapter 6, Problem 127E

Interpretation Introduction

Interpretation:

The maximum mass of iron that can be recovered from 10.0g of ore is to be determined.

Concept introduction:

$\text{Mass percent of element X= }\frac{\text{Mass of element X in 1 mol of compound}}{\text{Mass of 1 mol of compound}}\times 100$

Mass percent of Fe can be determined by substituting values in mass percent relation.

$\frac{\text{mass of compound}}{\text{molar mass of compound}}\text{=}\frac{\text{mass of element}}{\text{n×molar mass of element}}$

Where $\text{n}$ is the number of atoms of the element which the given compound can generate.
