\(m_{\text{bình tăng}}=m_{CO_2}=16.456\left(g\right)\)
\(n_{CO_2}=\dfrac{16.456}{44}=0.374\left(mol\right)\)
\(C_6H_{12}O_6\underrightarrow{^{\text{men rượu}}}2C_2H_5OH+2CO_2\)
\(0.187......................0.374.......0.374\)
\(m_{C_6H_{12}O_6}=0.187\cdot180=33.66\left(g\right)\)
\(m_{C_2H_5OH}=0.374\cdot46=17.204\left(g\right)\)

\(CO_2 + Ca(OH)2 \to CaCO_3 + H_2O\\ m_{CO_2}= m_{bình\ tăng} = 16,456(gam)\\ \Rightarrow n_{CO_2}= \dfrac{16,456}{44} = 0,374(mol)\\ C_6H_{12}O_6 \xrightarrow{t^o,xt} 2CO_2 + 2C_2H_5OH\\ n_{glucozo} = \dfrac{1}{2}n_{CO_2} = 0,187(mol) \Rightarrow m_{glucozo} = 0,187.180 = 33,66(gam)\\ n_{C_2H_5OH} = n_{CO_2} = 0,374(mol) \Rightarrow m_{C_2H_5OH} = 0,374.46 = 17,204(gam)\)
