The empirical formula represents the simplest whole number ratio of atoms in a compound.

Here's how to find the empirical formula for C₁₂H₈:

1. Find the greatest common factor (GCD) of the subscripts: The GCD of 12 and 8 is 4.

2. Divide each subscript by the GCD:

* C₁₂ / 4 = C₃

* H₈ / 4 = H₂

Therefore, the empirical formula of the compound with molecular formula C₁₂H₈ is C₃H₂.
