Chapter 13, Problem

Interpretation Introduction

Interpretation: The mass of $\text{NaCl}$ present in $9.63g$ of solution is to be calculated.

Concept introduction: Mass percent is the ratio of mass of solute to the mass of solution and multiplied it by $100\%$.

Mathematically, the mass percent of a solution is expressed as :

$\text{Mass percent}=\frac{\text{mass solute}}{\text{mass solute}+\text{mass solvent}}\times 100\%$

Mass percent of a solution is used as a conversion factor between the mass of a solute and mass of the solution.
