Theo PTHH : 

\(n_{C_6H_{12}O_6} = n.n_{tinh\ bột\ pư} = n.\dfrac{100}{162n}.80\%= \dfrac{40}{81}mol\)

\(n_{C_6H_{12}O_6\ pư} = \dfrac{40}{81}.75\% = \dfrac{10}{27}mol\\ \Rightarrow n_{C_2H_5OH} = 2n_{C_6H_{12}O_6\ pư} = 2. \dfrac{10}{27}= \dfrac{20}{27}mol\\ \Rightarrow m_{C_2H_5OH} = \dfrac{20}{27}.46 = 34,074(kg)\)
