For the reaction CH4 + 2 O2 - CO2 + 2 H2O, how many moles of H2O are formed when 20.0 moles of CH4 are burned? Show all work.?

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

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.
