What is the empirical formula of caffeine?

1 Answer

"C"_4"H"_5"N"_2"O"C4H5N2O

Explanation:

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

C_8H_10N_4O_2C8H10N4O2

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_2OC4H5N2O

This is the Empirical Formula.

I hope this was beneficial.
