The number of moles of methane required to produce (11 ~g CO_2(~g))...

The number of moles of methane required to produce (11 \mathrm{~g} \mathrm{CO}_2(\mathrm{~g})) after complete combustion is : (Given molar mass of methane in (\mathrm{g} \mathrm{mol}^{-1}: 16))

Step-by-step solution

$\mathrm{C}_{\mathrm{n}} \mathrm{H}_{2 \mathrm{n}+2}+\frac{3 \mathrm{n}+1}{2} \mathrm{O}_2 \longrightarrow \mathrm{nCO}_2+(\mathrm{n}+1) \mathrm{H}_2 \mathrm{O}$

$0.25 \mathrm{~mol~} \mathrm{CH}_4$ gives $0.25 \mathrm{~mole}$ (or $11 \mathrm{gm}$ ) $\mathrm{CO}_2$
