Chapter 7, Problem 7.83AP

Interpretation Introduction

Interpretation:

The concentration of solution formed by diluting hydrochloric acid has to be calculated.

Concept Introduction:

Molarity:  Molarity is defined as the mass of solute in one liter of solution.  Molarity is the preferred concentration unit for stoichiometry calculations.  The formula is,

  $\text{Molarity=}\frac{\text{Mass}\text{of}\text{solute(in}\text{moles)}}{\text{Volume}\text{of}\text{solution}\text{(in}\text{litres)}}$

Concentration of the solution is calculated using the formula,

  ${\text{M}}_{\text{1}}{\text{V}}_{\text{1}}{\text{=M}}_{\text{2}}{\text{V}}_{\text{2}}$

${\text{M}}_{\text{1}}\text{=}$ Initial molarity of the solution

${\text{V}}_{\text{1}}\text{=}$ Initial volume of the solution

${\text{M}}_{\text{2}}\text{=}$ Final molarity of the solution

${\text{V}}_{\text{2}}\text{=}$ Final volume of the solution
