2.1 g of caffeine (CsHioO2N4) undergoes a complete combustion in a calorimeter filled with water. The calorimeter assembly has a heat capacity of 4.2 BTU K-1 and the standard heat of combustion of caffeine is -1014.2 kcal mol1. How much water (liter) is inside the calorimeter if the temperature increases from 74.9°F to 78°F? What is the heat of formation of caffeine? Assume: water is liquid state and nitrogen does not combust
