Answer:
C₂H₄O
Explanation:
Empirical formulas show the simplest ratio of atoms in a compound in whole numbers.
We can think that all the atoms are divisible by 4.
As we need the lowest number for each subscript, empirical formula is:
C₂H₄O
We have divided, 8/4 for carbon, 16/4 for H and 4/4 for O.
The empirical formula is also known as the simplest expression to represent a chemical
