10.0 grams of propane combust in 32.0 L of oxygen gas at 2.5 atm and 635 celsius.?

Determine the total volume of gas present at the end of the reaction!!

uh.. so far (if I did it right) I balanced it as

C3H8 + 5O2 --> 3CO2 + 4H2O

then I converted propane into moles, which is .2267 mol C3H8

and I used PV = nRT for oxygen to get 1.053 mol O2

what do I do now?!?!?
