Ta có: \(n_C=n_{CO_2}=0,09\left(mol\right)\) \(\Rightarrow m_C=0,09.12=1,08\left(g\right)\)
\(n_H=2n_{H_2O}=0,08\left(mol\right)\) \(\Rightarrow m_H=0,08\left(g\right)\)
\(\Rightarrow\left\{{}\begin{matrix}\%m_C=\dfrac{1,08}{1,32}.100\%\approx81,82\%\\\%m_H=\dfrac{0,08}{1,32}.100\%\approx6,06\%\\\%m_O\approx12,12\%\end{matrix}\right.\)
