if 10.5 moles of CH4 react with oxygen, what is the volume of CO2 (in liters) produced at 20.9 degrees celsius and 0.951 atm?

1 answer

CH4 + 2O2 --> CO2 + 2H2O
mols CH4 = 10.4
Using the coefficients in the balanced equation, convert mols CH4 to mols CO2.

Then use PV = nRT and convert mols CO2 at the conditions listed to volume in L.
