# What is the empirical formula of Vanillin?

Oct 21, 2015

The same as its molecular formula: ${C}_{8} {H}_{8} {O}_{3}$.

#### Explanation:

The empirical formula of Vanillin is the same as its molecular formula: ${C}_{8} {H}_{8} {O}_{3}$.

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 ${C}_{6} {H}_{12} {O}_{6}$ is $C {H}_{2} O$. 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 $8 \mathmr{and} 3$ and obtain whole numbers, therefore, in this case the empirical formula is the same as the molecular formula.
