Ta có: \(n_{C_6H_5OH}=n_{NaOH}=0,05.2=0,1\left(mol\right)\)
⇒ nC6H5OH (trong 10,1g) = 0,05 (mol)
⇒ mancol = 10,1 - 0,05.94 = 5,4 (g)
Có: \(\Sigma n_{H_2}=\dfrac{1,12}{22,4}=0,05\left(mol\right)\)
⇒ nH2 (do ancol pư tạo thành) = 0,05.2 - 0,05 = 0,05 (mol)
\(\Rightarrow M_{ancol}=\dfrac{5,4}{0,05}=108\left(g/mol\right)\)
⇒ Ancol thơm đó là C6H5-CH2OH
\(\Rightarrow\left\{{}\begin{matrix}\%m_{C_6H_5OH}=\dfrac{0,05.94}{10,1}.100\%\approx46,5\%\\\%m_{C_6H_5-CH_2OH}\approx53,5\%\end{matrix}\right.\)
