Question

What is the empirical formula of caffeine?

Answer 1

`"C"_4"H"_5"N"_2"O"`

Explanation:

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

`C_8H_10N_4O_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_4H_5N_2O`

This is the Empirical Formula.

I hope this was beneficial.
