Chapter 11, Problem 63QP

Interpretation Introduction

Interpretation:

The molality for the given $\text{NaCl}$ solution in water is to be calculated.

Concept Introduction:

$\text{NaCl}$ is a strong electrolyte and is easily soluble in water as a consequence of ion-dipole force between water molecules and ions. Molality is the ratio of moles of solute and the mass of solvent in kilogram. The unit of molality is expressed as ${\text{mol kg}}^{-1}$ .
