Bomb Calorimetry and Food Science Food energy is defined as the amount of energy obtained from food that is available through cellular respiration. Laboratories use bomb calorimeters to measure the total or gross energy value of various food macronutrients. Food energy is then based on the heat of combustion, determined by the bomb calorimeter, and corrections that take into consideration the efficiency of digestion and absorption and the production of urea and other substances in the urine. Note that one food calorie (or 1kcal ) is equal to 4.184 kilojoules. Question 4 (1 point) When a 4.055-g sample of margarine is burned with excess oxygen in a bomb calorimeter with a heat capacity of 22.35kJK1. The temperature of the calorimeter rises from 18.76C to 37.42C. What is the Urxn value, in units of kJ/g, for the combustion of this margarine sample? Enter your numerical answer only (no units) to the correct amount of significant figures. Your
