Chapter 4, Problem 51E

Interpretation Introduction

Interpretation: The mass percent of ${\text{Al}}_{\text{2}}{\left({\text{SO}}_{\text{4}}\right)}_{\text{3}}$ in the sample is to be calculated.

Concept introduction: The ratio of the mass of a compound in the sample of mixture containing two or more compounds to the total mass of the mixture multiplied by $100$ gives the mass percentage of the compound in the total mixture. The mathematical expression for the mass percent is shown below.

  $\text{Mass}\text{percent}=\frac{\text{Mass of compound}}{\text{Total}\text{Mass of sample}}\times 100$
