Question:

A bomb calorimetric experiment was run to determine the enthalpy of combustion of ethanol. The reaction is CH5OH() + 3 0(g) 2 CO(g) + 3 HO(l)

The bomb had a heat capacity of 550 J/K, and the calorimeter contained 650 g of water. Burning 4.20 g of ethanol, C₂H₅OH(ℓ) resulted in a rise in temperature from 18.5°C to 22.3°C. Calculate ∆U for the combustion of ethanol, in kJ/mol.
