What is the quantity of glucose obtained when $68.4 \mathrm{~g}$ of sucrose is hydrolyzed in laboratory under ideal condition ? (molar mass of sucrose $=342 \mathrm{~g} \mathrm{~mol}^{-1}$ )
  1. $198 \cdot 0 \mathrm{~g}$
  2. $180 \mathrm{~g}$
  3. $68 \cdot 4 \mathrm{~g}$
  4. $36 \cdot 0 \mathrm{~g}$

Solution

$342 \mathrm{~g}$ of sucrose gives $180 \mathrm{~g}$ of glucose. $\therefore 68.4 \mathrm{~g}$ of sucrose gives $\frac{180 \times 68.4}{342}=36 \mathrm{~g}$ of glucose.
