Trong 1 mol acetic acid:
\(\left\{{}\begin{matrix}m_C=60.40\%=24\left(g\right)\\m_H=60.6,67\%=4\left(g\right)\\m_O=60-24-4=32\left(g\right)\end{matrix}\right.\Rightarrow\left\{{}\begin{matrix}n_C=\dfrac{24}{12}=2\left(mol\right)\\n_H=\dfrac{4}{1}=4\left(mol\right)\\n_O=\dfrac{32}{16}=2\left(mol\right)\end{matrix}\right.\)
Vậy CTHH là \(C_2H_4O_2\)
