Volume of Gas by Burning Gasoline

[korneld]

What is the volume of gas produced for a unit of gasoline burnt?

It is straight forward to calculate it. Just insert molecular weights in this and use 1 molar volume of a gas is 22.41 liters at STP.

2·C8H18 + 25·O2 => 16·CO2 + 18·H2O

Thanks for that. Isn't that 9 H2O, though?

Can't be, 2 moles of octane were combust in that formula.
