Before a bomb calorimeter can be used to analyze the heat of combustion of an unknown, the heat capacity of the calorimeter must be determined. One standard that is used in bomb calorimetry is 2,2,4-trimethylpentane (“isooctane”, C8H18). The change in internal energy (deltaE) per gram of combusted isooctane is -47.71 kJ/g. Suppose 0.692 g of octane is combusted in a bomb calorimeter with a heat capacity of 9.98 kJ/degree C. The initial temperature of the calorimeter before the combustion is 25.00 degrees C. Assuming no heat is lost to the outside of the calorimeter, what should be the final temperature of the calorimeter after the reaction?
