Acetic acid has 2 carbon, 4 hydrogen, and 2 oxygen atoms per molecule. What is the empirical formula for acetic acid?

Answer 1

The empirical formula is the simplest whole number ratio that defines constituent atoms in a species.

Given the defintion, the empirical formula of #H_3C-CO_2H, C_2H_4O_2#, #=# #CH_2O#. The molecular formula, as it is here, is always a multiple of the empirical formula.
