# What is the empirical formula for the following compounds?

## A) $N {a}_{2} {O}_{2}$ B) ${C}_{8} {H}_{6} {O}_{4}$ C) ${C}_{12} {H}_{12} {N}_{2} {O}_{3}$ D) ${C}_{4} {H}_{6} C {l}_{2}$

A. $N a O$
B. ${C}_{4} {H}_{3} {O}_{2}$
C. ${C}_{12} {H}_{12} {N}_{2} {O}_{3}$
D. ${C}_{2} {H}_{3} C l$

#### Explanation:

An empirical formula is the lowest ratio of the elements in a compound.

So for each of the compounds above, the GCF of the elements was used to divide the number of the atoms of each element in the formulas of the compounds.
