2. Sometimes, athletes illegally use anabolic steroids to increase muscle strength. A forensic chemist analyzes some tablets suspected of being a popular steroid. He determined that the substance in the tablets contains only carbon, hydrogen, and oxygen in and has a molar mass of 300.14 g/mole. When a 1.200 g sample of this study by combustion analysis, 3.516 g of CO₂ and 1.007 g of H₂O are collected. What is the molecular formula for the substance?
