Answer:
 Empirical formula of C₈H₈ = CH
Step-by-step explanation:
Data Given: 
Molecular Formula = C₈H₈
Empirical Formula = ?
Solution
Empirical Formula:
Empirical formula is the simplest ration of atoms in the molecule but not all numbers of atoms in a compound. 
So,
tha ration of the molecular formula should be divided by whole number to get the simplest ratio of molecule 
  C₈H₈ Consist of Carbon (C), and Hydrogen (H)
Now
Look at the ratio of these two atoms in the compound
 C : H 
 8 : 8 
Divide the ratio by two to get simplest ratio
 C : H 
 8/8 : 8/8 
 1 : 1
So for the empirical formula is the simplest ratio of carbon to hydrogen 1 : 1
So the empirical formula will be
 Empirical formula of C₈H₈ = CH
