A car gets 9.2 kilometers to a liter of gasoline. Assuming that gasoline is 100% octane C8H18(which has a density of 0.69g/cm3), how many liter of air(21% oxygen by volume) will be required to burn the gasoline for a 1250-km trip? Assume complete combustion. STP conditions can be assumed for the O2 gas consumed in this problem (1mol = 22.4 L - This equality can only be used for substances in the gaseous state).
