Chapter 4, Problem 61QP

Interpretation Introduction

Interpretation:

The number of moles of ${\text{MgCl}}_{\text{2}}$ in the solution is to be calculated.

Concept introduction:

The concentration of a solution is defined as the amount of solute present in a known volume of the solvent. Molarity is the unit used to express the concentration of a solution.

Molarity is the number of moles of the solute per liter of the solution.

$\text{Molarity}\left(\text{M}\right)\text{=}\frac{\text{moles of solute}}{\text{volume}\left(\text{L}\right)}$

The equation can be rearranged to calculate the volume of the solution or the number of moles of the solute.
