Chapter 14.4, Problem 14.4P

Interpretation Introduction

Interpretation:

Mass percent of ${\text{Na}}_{\text{2}}{\text{SO}}_{\text{4}}$ is solution that is prepared by dissolution of $25.0\text{ g}$ of ${\text{Na}}_{\text{2}}{\text{SO}}_{\text{4}}$ in $225.0\text{ g}$ of ${\text{H}}_{\text{2}}\text{O}$ has to be determined.

Concept Introduction:

Mass percent is concentration term used to determine concentration of solution in terms of solute percent in particular mass of solution. The expression for mass percent of species is as follows:

  $\text{Mass percent}=\left(\frac{\text{Mass of solute}}{\text{Mass of solution}}\right)\left(100\right)$
