Chapter 4, Problem 104QP

Interpretation Introduction

Interpretation:

The number of moles of $\text{Mg}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}$ , ${\text{Mg}}^{2+}$ , and ${\text{NO}}_3^{-}$ is to be determined.

Concept Introduction:

The conversion of volume from milliliters to liters is given as follows:

$\text{Volume}\left(\text{L}\right)=x\cancel{\text{mL}}\times \frac{\text{1 L}}{1000\cancel{\text{mL}}}$ …… (1)

The molarity of the solution is determined by the following expression:

$M=\frac{n}{V}$ …… (2)

Here, $n$ is the number of moles of solute, $V$ is the volume of the solution in liters, and $M$ is the molarity of the solution.
