What is the quantity of sugar charcoal obtained when $34.2 \mathrm{~g}$ sugar is charred using required quantity of conc. sulphuric acid under ideal conditions?
$114 \mathrm{~g}$
$14.4 \mathrm{~g}$
$11.0 \mathrm{~g}$
$10.5 \mathrm{~g}$
Solution
$\begin{aligned} & \mathrm{C}_{12} \mathrm{H}_{22} \mathrm{O}_{11} \rightarrow 12 \mathrm{C} \\ & \frac{34.2}{342}=0.1 \mathrm{~mol} 1.2 \mathrm{~mol} \\ & \therefore \text { Mass of charcoal is }=1.2 \times 12 \\ & =14.4 \mathrm{~g}\end{aligned}$
