Chapter 4, Problem 69QP

Interpretation Introduction

Interpretation:

A solution of $0.200{\text{M HNO}}_3$ is to be prepared from a $\text{4}{\text{.00 M HNO}}_3$ solution.

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.

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