Interpretation Introduction

Interpretation:

The number of ${\text{SO}}_{\text{4}}{}^{\text{2-}}$ and ${\text{Na}}^{\text{+}}$ ions present in one mole of ${\text{Na}}_{\text{2}}{\text{SO}}_{\text{4}}$ should be determined.

Concept Introduction:

Moles: One mole is equivalent to the mass of the substance consists same number of units equal to the atoms present in $\text{12}\text{g}$ of ${}^{\text{12}}\text{C}$.

The mole is actually quantity of particles that is Avogadro’s number of particles present in elements or compounds.
