Chapter 4, Problem 18E

Interpretation Introduction

Interpretation: The composition of $\text{2}\text{.0}\text{L}$ of $\text{3}\text{.00}\text{M}\text{HCl}$ is to be determined. The difference in $\text{2}\text{.0}\text{L}$ of $\text{3}\text{.00}\text{M}{\text{HC}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}$ with the same quantity $\text{HCl}$ is to be stated.

Concept introduction: Any substance’s composition can be conveniently explained using mass percentages of its constituent species. Different substances have different chemical composition which is demonstrated by the variation in mass percentage of their constituent species. For example, the mass percentage of $\text{X}$ present in compounds ${\text{XY}}_{\text{3}}\text{Z}$ is deduced by implying the formula shown below.

  $\text{Mass}\text{percentage}=\frac{\text{Mass}\text{of}\text{X}}{\text{Mass}\text{of}{\text{XY}}_{\text{3}}\text{Z}}\times 100\%$
