1 mole of Carbon monoxide gas are produced by each mole of methane burned
Further explanation
Given
Combustion of methane
Required
moles of Carbon monoxide
Solution
Complete combustion of Hydrocarbons with Oxygen will be obtained by CO₂ and H₂O compounds.
If O₂ is insufficient there will be incomplete combustion produced by CO and H₂O
Reaction
2CH4 + 3O2 → 2CO + 4H2O
From the equation, mol ratio of CH4 : CO = 2 : 2, so mol CO = mol CH4 = 1 mole
