How many moles of methane are required to produce 22g co2 after combustion

(Not guaranteed correct answer)

Balanced equation for complete combustion of methane would be:

CH4 + 2O2 - - > CO2 + 2H20

Amount of CO2:

22g / [12.0+2 (16.0) ]

= 0.5mol

Mole ratio can be represented as

CH4 = CO2

So 0.5 mol of CO2 = 0.5 mol of CH4?
