A chemical engineer studying the properties of fuels placed 1.150 g of a hydrocarbon in the bomb of a calorimeter and ﬁlled it with 02 gas. The bomb was immersed in 2.550 L of water and the reaction initiated. The water temperature rose from 20.00°C to 23.55°C. If the calorimeter (excluding the water)
had a heat capacity of 403 J/K, what was the heat of reaction for combustion (qV) per gram of the fuel?
(d for water = 1.00 g/mL; c for water = 4.184 J/g C.) Enter your answer in scientiﬁc notation.
