A 218 G Sample of Ethanol (C₂H₅OH)is Burned in a Bomb

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 $\mathrm { mol } ^ { - 1 }$ . C₂H₅OH(l) + 3O₂(g) ? 2CO₂(g) + 3H₂O(g) $D _ { \mathrm { r } }$ U = -1235 kJ mol^-1

A) 4.99 kJ °C^-1
B) 5.65 kJ °C^-1
C) 63.7 kJ °C^-1
D) 33.1 kJ °C^-1
E) 15.7 kJ °C^-1
