Gram for gram, fats in food have much more chemical energy than sugar. One component of fat is stearic acid, C18H36O2. When a sample of 1.02 g of stearicd acid was burned completely in a bomb calorimeter, the temperature of the calorimeter rose by 4.26 oC. The heat capacity of the calorimeter was 9.43 kJ/oC. Calculate the molar heat of combustion of stearic acid in kilojoules per mole. answer: (-11189 kJ/mol)

Given: The mass of stearic acid burned = 1.02 g The heat capacity of the calorimeter = 9.43 kJ/oC…
