(a)

Interpretation Introduction

Interpretation:

For the given compounds, empirical formula has to be written.

Concept introduction:

• Empirical formula is defined as least possible positive number ratio of atoms in a compound
• It does not indicate number or position of atoms in the compound
• $\text{Empirical}\text{formula}\text{of}{\text{C}}_{\text{6}}{\text{H}}_{\text{12}}\text{,}{\text{C}}_{\text{5}}{\text{H}}_{\text{10}}\text{is}{\text{CH}}_{\text{2}}$
• ${\text{Empirical formula of H}}_{\text{2}}{\text{S}}_{\text{2}}{\text{O}}_{\text{6}}\text{is}{\text{HSO}}_{\text{3}}$

To calculate: The empirical formula of ${\text{Al}}_{\text{2}}{\text{Br}}_{\text{6}}$
