Question

A substance has a molecular formula of `C_8H_10N_4O_2`. What is the empirical formula?

Answer 1

`C_4H_5N_2O`

Explanation:

The empirical formula is the simplest whole number ratio that defines constituent atoms in a species. The molecular formula is always a multiple of the empirical formula. We divide the molecular formula by `2` to get the empirical formula.
