Chapter 4, Problem 19E

Interpretation Introduction

Interpretation: The molarity of the final solution obtained by mixing $\text{50}\text{.0}\text{mL}$ of $\text{0}\text{.100}\text{M}{\text{HNO}}_{\text{3}}$ and $\text{100}\text{.0}\text{mL}$ of $\text{0}\text{.200}\text{M}{\text{HNO}}_{\text{3}}$ is to be calculated.

Concept introduction: The calculation of any solution’s molarity requires prior information of the solute’s moles and solution’s volume. The two when divided gives the solution’s concentration as molarity. When two solutions get mixed, the moles of the particular species involved get added. Higher solute’s moles result in higher solution’s molarity.
