A student wished to determine whether fats or sugars had the higher energy content. Small samples of stearic acid, CisH6O2(s) (a fatty acid) or sucrose, C12H22O1(s) (a sugar) were burned and the data collected as shown below. Sucrose Stearic Acid Mass of sample 1.55 g 1.17 g Calorimeter constant (heat capacity) Initial temperature of calorimeter 8.57 kJ/°C 24.30°C 8.57 kJ/°C 26.40°C Final temperature of calorimeter 27.88°C 30.28°C a. b. Use the data collected to calculate the enthalpy of combustion for 1.00 g of each substance. (4 marks) The student decided that a diet should consist of food with the highest energy content. Based on your calculations, which foods would be better in the student's diet. Explain. (3 marks) Identify one problem/concern with the diet proposed in part b.
