Question

How many liters of water can be produced from 5.0
liters of butane gas at STP, assuming excess oxygen?
C4H10(g) + 02(g) → CO2 (e) + H2O (g)​

Answer 1

you first have to balance out the equation
The coefficients would be 2,13,8,10

So for each mole of butane u have 5 moles of Water.(or for each liter because it’s in STP). Thus 5 liters would give u 25 liters of water. I attached the pic of the more detailed solution. Hope it helps:)
