Chapter 2, Problem 2.57QP

Interpretation Introduction

Interpretation: $10.0\text{g}$ of sulfur dioxide is given to be formed when $5.0\text{g}$ of sulfur combines with $5.0\text{g}$ of oxygen. The mass of oxygen required to convert $5.0\text{g}$ of sulfur into sulfur trioxide $\left({\text{SO}}_3\right)$ is to be calculated.

Concept introduction: The law of multiple proportions state that, “when two elements combine with each other to form two or more compounds, the ratios of the masses of one element that combines with fixed mass of other, are simple whole number ratios”.

To determine: The mass of oxygen required to react with $5.0\text{g}$ of sulfur to form sulfur trioxide $\left({\text{SO}}_3\right)$.
