During an experiment, the combustion of $1.45\,\text{g}$ ($0.025\,\text{mol}$) of propanone was used to warm $100\,\text{g}$ of water. The water began at $20.0^\circ\text{C}$ and ended at $78.0^\circ\text{C}$. What experimental value for the enthalpy change of combustion of propanone can be obtained from these data?
- A$-1304\,\text{kJ mol}^{-1}$
- B$-970\,\text{kJ mol}^{-1}$
- C$-352\,\text{kJ mol}^{-1}$
- D$-24.2\,\text{kJ mol}^{-1}$
