A 0.3423 g sample of pentane, C5H12. was burned in a bomb calorimeter. The temperature of the calorimeter and the 1.000 kg of water contained therein rose from 20.22°C to 22.82°C. The heat capacity of the calorimeter is 2.21 kJ/C. The heat capacity of water = 4.184 J/g.C. What is the heat of combustion, in kilojoules, per gram of pentane?
