CH₄ + 2 O₂ → CO₂ + 2 H₂O
According to the equation, mole ratio CH₄ : H₂O = 1 : 2
No. of moles of CH₄ burned = 20.0 mol
No. of moles of H₂O formed = (20.0 mol) × 2 = 40.0 mol
According to the equation, mole ratio CH₄ : H₂O = 1 : 2
No. of moles of CH₄ burned = 20.0 mol
No. of moles of H₂O formed = (20.0 mol) × 2 = 40.0 mol

CH4 + 2 O2 ----> CO2 + 2 H2O.
1 mole CH4 produces 2 moles H2O so,
20.0 moles CH4 produces
2 * 20.0 moles = 40.0 moles H2O.
1 mole CH4 produces 2 moles H2O so,
20.0 moles CH4 produces
2 * 20.0 moles = 40.0 moles H2O.
