Chapter 4, Problem 4.13P

Interpretation Introduction

Interpretation:

For diluting a $10.0M$ solution to a $1.00M$ solution whether the instruction: “take $100.0\text{ mL}$ of the $10.0M$ solution and add $900.0\text{ mL}$ water” is correct or not is to be explained.

Concept introduction:

Molarity $\left(M\right)$ is one of the concentration terms that determine the number of moles of solute present in per liter of solution. Unit of molarity is $\text{mol/L}$.

The expression to calculate the molarity of a solution when moles of solute and volume of solution are given is as follows:

$\text{Molarity of solution}\left(M\right)=\frac{\text{moles of solute}\left(\text{mol}\right)}{\text{volume of solution}\left(\text{L}\right)}$

Dilution is the process of converting a concentrated solution into a dilute solution by adding more solvent. In the resultant solution, the amount of solute remain fixed but the volume of the solution increases resulting in a less concentrated solution.
