Số mol glucozo:
n= \(\frac{1000.90\%}{162}=\frac{50}{9}\left(mol\right)\)
Gỉa sử ancol 100 độ thì:
nC2H5OH= 2.n= 2.50/9= 100/9(mol)
=> mC2H5OH= 100/9 . 46 \(\approx511,111\left(g\right)\)
Sơ đồ phản ứng:
\(C_6H_{10}O_5\rightarrow C_6H_{12}O_6\rightarrow2C_2H_5OH+CO_2\)
Ta có:
\(n_{C6H10O5}=1000=90\%=900\left(g\right)\)
\(\Rightarrow n_{C6H10O5}=\frac{900}{162}=\frac{50}{9}\left(mol\right)\)
\(\Rightarrow n_{C2H5OH}=2n_{C6H10O5}=\frac{100}{9}\left(mol\right)\)
\(\Rightarrow m_{C2H5OH}=\frac{100}{9}.46=511,11\left(g\right)\)
