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