Chapter 14, Problem 81AE

Interpretation Introduction

Interpretation:

Molality and molarity of solution that has $38{\text{ \% H}}_2{\text{SO}}_4$ and density of $1.29\text{ g/mL}$ has to be determined.

Concept Introduction:

Molality is amount of solute present in $1\text{ kg}$ of solvent. Expression for molality of solution is as follows:

  $\text{Molality of solution}=\frac{\text{Moles of solute}}{\text{Mass }\left(\text{kg}\right)\text{of solvent}}$

Molarity is amount of solute present in $1\text{ L}$ of solution. Formula for molarity of solution is as follows:

  $\text{Molarity of solution}=\frac{\text{Moles of solute}}{\text{Volume }\left(\text{L}\right)\text{ of solution}}$
