Octane is a primary constituent of gasoline, burn in air according to the following reaction: C8H18 (1) + 25/2 O2 (g) -> 8 CO2 (g) + 9 H₂O (1) A 69 -g sample of octane is burned in a constant volume calorimeter. The calorimeter is in an insulated container with 1.20 kg of water. The temperature of the water and the bomb rises from 25.00 °C to 33.20 °C. The heat required to raise the bombs temperature (its heat capacity). Cbomb, is 837 J/K. Determine the heat of combustion per gram of octane. Cwater = 4.184 Jak
