A 35.6 g sample of ethanol (C2H5OH) is burned in a bomb calorimeter according to the following reaction. If the temperature rose from 35.0 °C to 76.0°C and the heat capacity of the calorimeter is 23.3 kJ °C-1, what is the value of DrU°? The molar mass of ethanol is 46.07 g mol-1.

C2H5OH(l) + 3O2(g) → 2CO2(g) + 3H2O(g)DrU° = ?

◦ -8.09 × 103 kJ mol-1
◦ -9.55 × 103 kJ mol-1
◦ +9.55 × 103 kJ mol-1
◦ -1.24 × 103 kJ mol-1
◦ +1.24 × 103 kJ mol-1
