answer is 0.5 mol.
1) formula for the complete combustion of methane with oxygen: CH4+2O2 =CO2+2H2O
2) molecular mass ofCO2=12+2(16) =44g
3) combining 1 and 2, 1 mol CH4=44g(1mol) CO2.
4)by proportion 0.5 mol CH4 in complete combustion=22g CO2.
hope this helps u

Burning of Methane:
CH4 (g) + 2 O2 (g) ===> CO2 (g) + 2 H2 O (l) or (g)
1 mole 2 moles 1 mole = 44gm 2moles=36 gms
Molar mass of CO2 = 44.
So 1 mole of CH4 produces 1mole of CO2 or 44 gm of CO2.
Given that CO2 produced is 22 gm ?
So amount of CH4 needed, 22/44 = 1/2 mole of CH4 gas.
CH4 (g) + 2 O2 (g) ===> CO2 (g) + 2 H2 O (l) or (g)
1 mole 2 moles 1 mole = 44gm 2moles=36 gms
Molar mass of CO2 = 44.
So 1 mole of CH4 produces 1mole of CO2 or 44 gm of CO2.
