The empirical formula gives you the whole number ratio in which elements are present in a compound.

Explanation:

Example:

$C H_{2} O$ $CH_2O$ could be the empirical formula for:
$C H_{2} O$ $CH_2O$ formalin
$C_{2} H_{4} O_{2}$ $C_2H_4O_2$
$C_{3} H_{6} O_{3}$ $C_3H_6O_3$
.....
$C_{6} H_{12} O_{6}$ $C_6H_12O_6$ glucose or fructose, or...

The empirical number says nothing about real formula or structure.
