Tutored Practice Problem 5.4.4 Use constant-volume calorimetry to determine energy change. Close Problem A 0.394-g sample of pyrene (C16H10) is burned in a bomb calorimeter and the temperature increases from 24.60C to 27.70C. The calorimeter contains 1.02103g of water and the bomb has a heat capacity of 859J/C. Based on this experiment, calculate E for the combustion reaction per mole of pyrene burned (kJ/mol). C16H10(s)+37/2O2(g)16CO2(g)+
