# What is the empirical formula of caffeine?

May 15, 2014

$\text{C"_4"H"_5"N"_2"O}$

#### Explanation:

To find the empirical formula for caffeine we begin with the Molecular (true) Formula

${C}_{8} {H}_{10} {N}_{4} {O}_{2}$

We can then reduce the Molecular Formula to the Empirical (simple) Formula by dividing each of the subscripts by the greatest common factor. In this case we divide by 2.

${C}_{4} {H}_{5} {N}_{2} O$

This is the Empirical Formula.

I hope this was beneficial.
