Chapter 4, Problem 15PP

Interpretation Introduction

Interpretation:

The molarity of ${\text{H}}_2\text{S}$ solution is to be determined.

Concept Introduction:

The number of moles is calculated from the following expression:

$n=\frac{m}{M_m}$ …… (1)

Here, $m$ is the mass of solute, $M_m$ is the molar mass of solute, and $n$ is the number of moles of the solute.

The molarity of the solution is determined by the following expression:

$M=\frac{n}{V}$ …… (2)

Here, $n$ is the number of moles of solute, $V$ is the volume of the solution in liters, and $M$ is the molarity of the solution.
