Chapter 4.1, Problem 4.6AFP

Interpretation Introduction

Interpretation:

The final volume of $1.25M$ diluted solution obtained from $60.0\text{mL}$ of $4.50M$ potassium permanganate.

Concept introduction:

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

The expression to calculate the volume of diluted solution when molarity and volume of concentrated solution and molarity of diluted solution are given is as follows:

$V_{\text{dil}}=\frac{M_{\text{conc}}{V}_{\text{conc}}}{M_{\text{dil}}}$
