Chapter 4, Problem 103QP

Interpretation Introduction

Interpretation:

The number of moles of ${\text{Na}}_{\text{2}}{\text{SO}}_{\text{4}}$ , ${\text{Na}}^{+}$ , and ${\text{SO}}_4^{2-}$ is to be determined.

Concept Introduction:

The conversion of volume from milliliters to liters is given as follows:

$\text{Volume}\left(\text{L}\right)=x\cancel{\text{mL}}\times \frac{\text{1 L}}{1000\cancel{\text{mL}}}$ …… (1)

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.
