Sửa đề: 36 → 3,6
\(C_{12}H_{22}O_{11}+H_2O\underrightarrow{^{t^o,H^+}}C_6H_{12}O_6+C_6H_{12}O_6\)
Gọi: \(\left\{{}\begin{matrix}n_{C_6H_{12}O_6}=x\left(mol\right)\\n_{C_{12}H_{22}O_{11}}=y\left(mol\right)\end{matrix}\right.\) ⇒ 180x + 342y = 3,51 (1)
Theo PT: \(n_{C_6H_{12}O_6}=n_{C_{12}H_{22}O_{11}}=y\left(mol\right)\)
⇒ 180x + 180y + 180y = 3,6 (2)
Từ (1) và (2) \(\Rightarrow\left\{{}\begin{matrix}x=0,01\left(mol\right)\\y=0,005\left(mol\right)\end{matrix}\right.\)
\(\Rightarrow\left\{{}\begin{matrix}\%m_{C_6H_{12}O_6}=\dfrac{0,01.180}{3,51}.100\%\approx51,28\%\\\%m_{C_{12}H_{22}O_{11}}\approx48,72\%\end{matrix}\right.\)
