With the combustion of methane, CH4, If 150 Liters of carbon dioxide are produced, how many grams of methane required?
CH4+2O2>> CO2 + 2H2O
law of volumes applies..then if 150 liters carbon dioxide, one got then also 300 liters of water vapor, and used 150 liters of methane...
Now, grams of methane...At what temperature did all this occur, and pressure?
