Question

**When 0.187 g of benzene,C6H6, is burned in a bomb calorimeter, the surrounding water bath rises in temperature by 7.48 C. **


Assuming that the bath contains 250.0 g of water and that the calorimeter itself absorbs a negligible amount of heat, calculate combustion energies (Delta E) for benzene in both kilojoules per gram and kilojoules per mole.

Answer 1

q_v = mass H2O x specific heat x delta T = delta E.
This answer will be in J/g. I assume you know how to convert to kJ/g and kJ/mole.
