How many liters of methane gas (CH4) need to be combusted to produce 8.5 liters of water vapor, if all measurements are taken at the same temperature and pressure? Show all of the work used to solve this problem.

CH4 (g) + 2 O2 (g) yields CO2 (g) + 2 H2O (g)

?L-->8.5L of H2O
1 mole of CH4-->2moles of H2O vapor

1:2 ratio

now what do you think it might be
