A 21.8 g sample of ethanol (C2H5OH) is burned in a bomb calorimeter according to the following reaction. If the temperature rises from 25.0 °C to 62.3 °C, determine the heat capacity of the calorimeter. The molar mass of ethanol is 46.07 g mol-1. C2H5OH(l) + 3O2(g) → 2CO2(g) + 3H2O(g) ΔrU = -1235 kJ mol-1
A) 4.99 kJ °C-1
B) 5.65 kJ °C-1
C) 63.7 kJ °C-1
