Answer:
The answer to your question is 12 moles of water.
Step-by-step explanation:
Reaction
2 O₂ + CH₄ ⇒ CO₂ + 2 H₂O
If Oxygen is in excess, then the limiting reactant is methane and we calculate the moles of water produced considering the moles of methane.
1 mol of methane -------------- 2 moles of water
6 moles of methane --------- x
x = (6 x 2) / 1
x = 12 moles of water
