What is the quantity of water required to obtain one mole of glucose from one mole of sucrose by acid hydrolysis?
- $9.5 \mathrm{~g}$
- $18.0 \mathrm{~g}$
- $15.0 \mathrm{~g}$
- $16.0 \mathrm{~g}$
Solution
$\begin{aligned} & \mathrm{C}_{12} \mathrm{H}_{22} \mathrm{O}_{11}+\mathrm{H}_2 \mathrm{O} \stackrel{\mathrm{H}^{+}}{\longrightarrow} \mathrm{C}_6 \mathrm{H}_{12} \mathrm{O}_6+\mathrm{C}_6 \mathrm{H}_{12} \mathrm{O}_6 \\ & \text { Sucrose glucose fructose } \\ & 1 \mathrm{~mol} \quad 1 \mathrm{~mol} \\ & \text { Mole of } \mathrm{H}_2 \mathrm{O}=\text { Mole of glucose } \\ & \end{aligned}$
$\frac{w}{18}=1$
$\because w=18 \mathrm{~g}$
