Chapter 13, Problem 13.58P

(a)

Interpretation Introduction

Interpretation:

The molarity of the dilute solution of aqueous $\text{NaOH}$ is to be calculated.

Concept introduction:

Dilution is the process of converting a concentrated solution into a dilute solution by adding the solvent. In the resultant solution, the amount of solute remains fixed but the volume of the solution increases. The moles of solute before and after dilution remains fixed.

The formula to relate the molarity of a diluted and concentrated solution is as follows:

$M_{\text{conc}}{V}_{\text{conc}}=M_{\text{dil}}{V}_{\text{dil}}$ (1)

Here, $M_{\text{conc}}$ is the molarity of the concentrated solution.

$V_{\text{conc}}$ is the volume of the concentrated solution.

$M_{\text{dil}}$ is the molarity of a dilute solution.

$V_{{}_{\text{dil}}}$ is the volume of dilute solution.
