3. In the office, there were some burnt papers in the garbage bin. A nearly empty bottle of fuel was found nearby. The forensic scientist collected 7.50 gram of the fuel in the bottle and subjected it to complete combustion. Analysis of the gaseous result showed 23.18 g of carbon dioxide and 11.39g of water. Determine the empirical formula of the compound. Write the balanced chemical equation for the combustion of the compound in a). Calculate the mass of oxygen needed. . If the mass is less than 20.0 g, eliminate Justin Thyme. If the mass is more than 20.0 g, eliminate Amy Stake. Calculate the volume of CO₂ generated by SATP. . . If the volume is less than 15.0 L, eliminate Justin Thyme. . If the volume is more than 15.0 L eliminate Dinah Mite.
