Chapter 4, Problem 68QP

Interpretation Introduction

Interpretation:

The concentration of the final solution of ${\text{KNO}}_{\text{3}}$ is to be determined.

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:

$M_{\text{i}}\times V_{\text{i}}\text{ = }{M}_{\text{f}}\times V_{\text{f}}$

Here, $M_{\text{i}}$ is the initial concentration of solution in M, $M_{\text{f}}$ is the final concentration of solution inM, $V_{\text{i}}$ is the initial volume of solution in liters, and $V_{\text{f}}$ is the final volume of the solution in liters.
