Chapter 13, Problem 100E

Interpretation Introduction

Interpretation:

The molality of the given solution containing glucose and water is to be calculated.

Concept Introduction:

The concentration of the solution is expressed in terms of the molality $\left(m\right)$.

Molality is the number of moles of solute dissolved in the mass of solvent.

The mass of the solvent should be in kilograms $\left(\text{kg}\right)$.

Calculate molality as follows:

$m=\frac{\text{Moles solute}}{\text{Kilograms solvent}}$ …… (1)

The relation between density $\left(d\right)$ and volume $\left(V\right)$ is as follows:

$d=\frac{\text{mass}}{V}$…… (2)
