**DrBob222**, Sunday, October 3, 2010 at 8:36pmC7H8 + 9O2 ==> 7CO2 + 4H2O

1 gallon toluene = about 3,785 mL

density = about 0.867 g/mL

mass toluene = 3785 mL x 0.867 g/mL = 3282 grams.

moles toluene = grams/molar mass = 3282/92 = about 36 moles.

From the equation above, 1 mole C7H8 will produce 7 moles CO2; therefore, 36 moles toluene will produce 7 x 36 = about 250 moles CO2.

Then use PV = nRT, plug in P,n,R, and T and solve for liters (V). Redo my math above. I rounded here and there.
