Chapter 4, Problem 87E

Interpretation Introduction

Interpretation: The mass percent of the iron in the iron ore is to be calculated.

Concept introduction: The balanced redox reaction is helpful in determining the molarity and mass percent of the elements present in the reaction. The mass percent of a chemical compound is obtained from calculated mass of that compound to total mass of the entire compound.

The formula to calculate mass percent is shown below.

  $\text{Mass percent}\left(\%\right)=\frac{\text{Calculated mass}\text{g}}{\text{Total mass}\text{g}}\times 100$
