LPG fuel is actually a mixture of gases, but we want to calculate the estimated fuel consumption of a car assuming it is all propane. The following reaction is the combustion reaction of propane. If a normal car needs 20010 J of energy from Istanbul to Ankara, how many kg of propane will be consumed in this path? (molar mass: C 12, H 1.0-16)
C3H8 + 5 O2 ----> 3 CO2 + 4 H2O
ΔH = 2200 kJ/mol
