Answer:

The same as its molecular formula: #C_8H_8O_3#.

Explanation:

The empirical formula of Vanillin is the same as its molecular formula: #C_8H_8O_3#.

Empirical formula by definition is the simplest formula of a compound. It is determined by dividing all subscripts of all elements by the same integer and obtain whole numbers.

Example: The empirical formula of #C_6H_12O_6# is #CH_2O#. We can divide all subscripts by #6# and obtain whole numbers.

For vanillin, it is not possible to find a number where we can divide #8 and 3# and obtain whole numbers, therefore, in this case the empirical formula is the same as the molecular formula.
