Question
A 6.40 g sample of butane, C4H10(g), was burned in a bomb calorimeter in the presence of excess
oxygen. The calorimeter contained 4.86 kg of water. Calculate the heat exchanged with respect to
the system during the reaction if the calorimeter has a heat capacity of 254. J/°C and the
temperature of the calorimeter and water changed from 29.0°C to 43.2°C? Enter your answer to 3
significant figures in decimal form. Do not enter units since they are already given.
kJ
