Chapter 8, Problem 8.92AP

Summary Introduction

To determine:

The volume of $4\text{X}$ stock solution, that is added in $\text{800}\text{mL}$ of solution to make it $3\%$ concentrated.

Introduction:

Dilution of the solution means decreasing the concentration of the solution. By adding the extra volume of the solution the concentration of the solute decreases in the solution.

Dilution factor is the ratio of final volume of the solution to the initial volume.

The dilution factor is given by the expression,

$\text{Dilution}\text{factor}=\frac{\text{Final}\text{Volume}\text{of}\text{solution}}{\text{Intial}\text{volume}\text{of}\text{solution}}$

Summary Introduction

To determine:

The concentration of $\text{4X}$ stock solution, that is added to $\text{800}\text{mL}$ of solution to make it $3\%$ concentrated.

Introduction:

The relation between the volume of solution and concentration is given by the expression,

$\begin{array}{c}\left(\text{Initial}\text{concentration}\right)\left(\text{Initial}\text{volume}\text{of}\text{solution}\right)=\left(\text{Final}\text{concentration}\right)\\ \left(\text{Final}\text{volume}\text{of}\text{solution}\right)\end{array}$
