Chapter 11, Problem 66QP

Interpretation Introduction

Interpretation:

The Molar concentration of ions in $2.5\text{M}{\text{MgCl}}_2$ solution and molal concentration of $2.5\text{m}{\text{MgCl}}_2$ is to be determined.

Concept Introduction:

Molarity is used for expressing the strength of a solution. It is calculated by taking the ratio of moles of solute and the volume of the solution in liters. The molarity is expressed in ${\text{mol L}}^{-1}$ .

Molality is the ratio of moles of solute and the mass of solvent in kilograms. Molality is expressed in ${\text{mol kg}}^{-1}$ .
