Chapter 14, Problem 29E

Interpretation Introduction

Interpretation:

The molarity and molality of the solution needs to be determined.

Concept introduction:

The molarity of solution is defined as number of moles of solute in 1 L of the solution.

$M=\frac{n}{V\left(\text{L}\right)}$

The molality of solution is defined as number of moles of solute in 1 kg of the solvent. Thus,

$m=\frac{n}{M_{\text{solvent}}\left(\text{kg}\right)}$

Here, n is number of moles of solute and M is mass of solvent in Kg.
