Chapter 13, Problem 114E

Interpretation Introduction

Interpretation:

The concentration of $\text{HCl}$ in terms of mass percent is to be calculated.

Concept Introduction: Molarity of a substance is defined as the number of moles of solute dissolved in one liter of solution.

The relation between molarity $\left(\text{M}\right)$ and number of moles of a solution is:

$\text{M}=\frac{\text{moles solute}}{\text{L solution}}$

The relation between density $\left(d\right)$, mass and volume $\left(V\right)$ of solution is expressed as:

$d=\frac{\text{mass}}{V}$

Number of moles is equal to the ratio of mass of substance and molecular mass of a substance.

The relation between mass and molar mass is:

$n=\frac{\text{mass}}{\text{molar mass}}$

Mass percent is defined as the product of ratio of mass of solute to the mass of solution and hundred. It is expressed as follows:

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