2. Ethanol is used as a component in fuel for some vehicles. One fuel mixture contains 10% by
mass of ethanol in unleaded petrol (gasoline). This mixture is often referred to as Gasohol E10
a) Assume that the other 90% by mass of Gasohol E10 is octane. 1.00 kg of this fuel mixture
was burned.
CH, CH, OH(1) + 302(9) — 2002(9) + 3H2O(1)
AH = -1367 kJ molt
CH,30 + 12 029) — 8C02(9) +9H, O()
AH = -5470 kJ molt
(i) Calculate the mass, in g, of ethanol and octane in 1.00 kg of the fuel mixture!
