- Anabolic steroids are performance enhancement drugs whose use hasbeen banned from most major sporting activities. One anabolic steroidis fluoxymesterone (C20H29FO3). Calculate the percent composition bymass of fluoxymesterone.Physical and Biological SciencesA bomb calorimeter was calibrated by burning 1.013 g of benzoic acid(C7H6O2) (ΔUcomb = 3.221 × 103 kJ/mol). 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.
