Question

5) An experimenter used a bomb calorimeter to determine the enthalpy of combustion of octane. The expression used to calculate the enthalpy is given by: 17 where Ceal is the heat capacity of the calorimeter, n is the number of moles of octane, CsHis used and Ti and T are the initial and final temperatures of the combustion. The following data was collected by the researcher: Cal = 2390 +/-10k/PC T 24.02 +1-0.02 C Mass octane-54.32 +-01 g T;-25.16+/-0.02-C MWacta114.2302 g/mol a.) From this information, calculate the heat of combustion for octane. HomkJ/mol b.) Calculate the propagation of error value for the values given above. Error kJ/mol Both parts a and b please
