\(n_{CO2}=\frac{2,24}{22,4}=0,1\left(mol\right)\)
\(C_6H_{12}O_6\underrightarrow{^{t^o,men.ruoi}}2C_2H_5OH+2CO_2\)
0,05______________0,1_________0,1
Theo PT:
\(n_{C6H12O6}=\frac{1}{2}n_{CO2}=\frac{0,1}{2}=0,05\left(mol\right)\)
\(\Rightarrow m_{C6H12O6}=0,05.180=9\left(g\right)\)
\(\Rightarrow C\%_{glucozo}=\frac{9}{500}.100\%=1,8\%\)
Theo PT:
\(\Rightarrow n_{C2H5OH}=n_{CO2}=0,1\left(mol\right)\)
\(\Rightarrow m_{C2H5OH}=0,1.46=4,6\left(g\right)\)
\(m=D.V\Rightarrow V_{C2H5OH}=\frac{4,6}{0,8}=5,75\left(ml\right)\)
