\(n_{CH_3COOH}=\dfrac{9}{60}=0,15\left(mol\right)\\ n_{C_2H_5OH}=\dfrac{4,6}{46}=0,1\left(mol\right)\\ CH_3COOH+C_2H_5OH⇌CH_3COOC_2H_5+H_2O\\ LTL:\dfrac{0,15}{1}>\dfrac{0,1}{1}\\ \Rightarrow TínhtheosốmolC_2H_5OH\\\Rightarrow n_{CH_3COOC_2H_5\left(lt\right)}=n_{C_2H_5OH}=0,1\left(mol\right)\\ n_{CH_3COOC_2H_5\left(tt\right)}=\dfrac{6,6}{88}=0,075\left(mol\right)\\ \Rightarrow H=\dfrac{0,075}{0,1}.100=75\%\)
