Chapter 15, Problem 53AE

Interpretation Introduction

Interpretation:

Concentration of ${\text{Al}}^{3+}$ ion found in solution of ${\text{AlBr}}_3$ with $\text{0}{\text{.142 M Br}}^{-}$ has to be calculated.

Concept Introduction:

Molarity is quantitatively defined as moles of solute in one liter of solution. For example, $\text{0}{\text{.070 M AlCl}}_3$ indicates that in $1\text{ L}$ moles of ${\text{AlCl}}_3$ is $\text{0}\text{.070 mol}$. The formula to evaluate molarity is given as follows:

  $M=\frac{n}{V}$

Here,

$V$ represents volume.

$M$ represents molarity.

$n$ represents number of moles.
