Chapter 13, Problem 13.125QP

Interpretation Introduction

Interpretation

Density and molality of the solution has to be calculated.

Concept introduction

• Molality: Molality is defined as number of moles of the solute present in the kilogram of the solvent.

$\text{Molality =}\frac{\text{number of moles of the solute}}{\text{kg of solvent}}$

• Density is calculated by mass of the substance divided by its volume.

$\text{density =}\frac{\text{mass}}{\text{volume}}$
