Question

Suppose 1.319 grams of an organic compound of formula, C3H7O2, is combusted in a bomb calorimeter
with a heat capacity of 12.4 kJ/ 0C. Temperature of the calorimeter before the combustion was 17.91 0C
and that after the combustion the maximum temperature recorded was 20.13 0C.
a. Determine the enthalpy of combustion for this reaction.
b. Determine the enthalpy of formation for the organic compound of formula, C3H7O2
