In an experiment to calculate he enthalpy change of combustion of a fuel, 1.5g (0.0326 mol) of the fuel was used to heat 200g of water. The temperature of the water rose from 25'C to 55'C. The specific heat capacity of water is 4.18 J/Kg.
There is a significant heat loss in this experiment. Therefore, the experimental value for the enthalpy change of combustion of the fuel will be different from the theoretical value.
Using the information above, what is he experimental value for the enthalpy change of combustion of the fuel?
A. -1410 kJ/mol
B. -760 kJ/mol
C. -30.7 kJ/mol
D. -16.7 kJ/mol
