Minimum amount of ${\mathrm{Ag}}_2{\mathrm{CO}}_3\left(s\right)$ required to produce sufficient oxygen for the complete combustion of ${\mathrm{C}}_2{\mathrm{H}}_2$ which produces 11.35 litre of ${\mathrm{CO}}_2$ at STP after combustion is: $[Ag=108]$

$\begin{array}{l}{\mathrm{Ag}}_2{\mathrm{CO}}_3\left(\mathrm{s}\right)⟶2\mathrm{Ag}\left(s\right)+{\mathrm{CO}}_2\left(\mathrm{g}\right)+\frac{1}{2}{\mathrm{O}}_2\left(\mathrm{g}\right)\\ {\mathrm{C}}_2{\mathrm{H}}_2+\frac{5}{2}{\mathrm{O}}_2⟶2{\mathrm{CO}}_2+{\mathrm{H}}_2\mathrm{O}\end{array}$
