\(\left(C_6H_{10}O_5\right)_n+nH_2O\underrightarrow{^{axit}}nC_6H_{12}O_6\)
\(C_6H_{12}O_6\underrightarrow{^{men}}2C_2H_5OH+2CO_2\)
Ta có:
\(H=80\%.81\%=65,8\%\)
Sơ đồ : \(C_6H_{10}O_5\rightarrow C_6H_{12}O_6\rightarrow2C_2H_5OH\)
\(n_{C6H10O5}=\frac{1,5}{162}\Rightarrow n_{ancol\left(LT\right)}=\frac{1,5}{162}.2=\frac{3}{162}\left(mol\right)\)
\(\Rightarrow n_{ancol\left(tt\right)}=\frac{3}{162}.64,8\%=0,012\left(mol\right)\)
\(\Rightarrow m_{ancol}=0,012.46=0,552\left(g\right)\)
