The temperature change in thecalorimeter during the calibration combustion was 5.19°C. A nutritional chemist then used the calibrated calorimeter to determine the energy con-tent of food. The chemist carefully dried a sample of food and placed 0.8996 g of the sample in the calorimeter with sufficient oxygen for thecombustion to go to completion. Combustion of the food sample causedthe temperature of the calorimeter to increase by 4.42°C.1. Approximately how many moles of O2 gas were consumed in thecalibration combustion?a) 0.008 c) 0.2b) 0.1 d) 0.06 2. What is the heat capacity (CV) of the calorimeter?a) 5.15 kJ/°C c) 5.12 kJ/°Cb) 5.08 kJ/°C d) 4.97 kJ/°C3. What is the energy content of the food?a) 22.8 kJ/g c) 25.3 kJ/gb) 4.97 kJ/g d) 0.201 kJ/g4.
