What quantity of carbon dioxide is produced when 2 mole of carbon is burnt in $16 \mathrm{~g}$ of dioxygen?

What quantity of carbon dioxide is produced when 2 mole of carbon is burnt in $16 \mathrm{~g}$ of dioxygen?
  1. $44 \mathrm{~g}$
  2. $88 \mathrm{~g}$
  3. $11 \mathrm{~g}$
  4. $22 \mathrm{~g}$

Solution

$\begin{aligned} & \mathrm{C}+\mathrm{O}_2 \rightarrow \mathrm{CO}_2 \\ & 2 \mathrm{~mol} \frac{16}{32}=0.5 \mathrm{~mol} \\ & 0.5 \mathrm{~mol}(\mathrm{LR}) \\ & \text { Mass of } \mathrm{CO}_2 \text { produced is }=0.5 \times 44=22 \mathrm{~g}\end{aligned}$
