    a mole of gas in ideal conditions is 22.414 L you have 8.9L so divide by 22.414L, so you have 0.397 moles in the balanced equation you have a ratio methane:water, 1:2. so you have twice as many moles, 0.397*2= 0.794 moles of H2O vapour, convert that back to Liters by multiplying by 22.414 L and you have 17.8 L of water vapour

    you could've just multiplied the amount of litters by 2, but i wanted to show you where it came from
