Reaction

CH₄ (g) + 2O₂ (g) <=> CO₂ (g) + 2H₂O(g)

assume at STP ( 1 mole gas = 22.4 L)

for 20 L, moles of methane:

= 20 : 22.4 = 0.893

moles of water = 2/1 x mol methane = 2/1 x 0.893 = 1.786

mass of water = mol x molar mass = 1.786 x 18 g/mol = 32.148 g

Answer:

See below, please

Step-by-step explanation:

1 mol CH4 ——>2 mol H2O=2x18 g/mol= 36 g

The question is not clear. You should tell us the concentration of CH4, methane.
