Many home barbeques are fueled with propane gas C3H8.

What mass of carbon dioxide (in kg) is produced upon the complete combustion of 18.9L of propane (approximate contents of one 5-gallon tank)? Assume that the density of the liquid propane in the tank is 0.621g/ml.

How do I start & work this question?

I wrote a balanced equation:
C3H8 + 5O2 -> 4H2O + 3CO2

Now, where do I go from here?

  1. The propane is liquid. Determine the mass from the volume and liquid. Convert that mass to moles.

    For each mole of propane, you get (from the balanced equation) three times as much CO2. Convert moles of carbon dioxide to kg
