Chapter 4, Problem 67QP

Interpretation Introduction

Interpretation:

A solution of $0.646\text{ M HCl}$ is to be prepared from $2.00\text{ M HCl}$.

Concept introduction:

A solution is prepared by dissolving a known amount of solute in a specific amount of solvent.

The concentration of a solution is expressed in the unit of molarity. Molarity is the moles of solute per liter of the solution.

Throughdilution, a less concentrated solution is prepared from a more concentrated one. The solution can be diluted using the dilution formula:

$M_{\text{c}}\times V_{\text{c}}\text{ = }{M}_{\text{d}}\times V_{\text{d}}$

Here, $M_{\text{c}}$ is the concentration of concentrated solution in M, $M_{\text{d}}$ is the concentration of the diluted solution in M, $V_{\text{c}}$ is the volume of the concentrated solution in liters, and $V_{\text{d}}$ is the volume of the diluted solution in liters.
