An unknown compound contains carbon, hydrogen, oxygen, and sulfur atoms. When a 10.00 mg sample of the unknown compound was combusted, it produced 16.27 mg of CO2, 5.55 mg of water, and 7.90 mg of SO2. What is the empirical formula of the unknown compound? The Hans-On Science Center (HOSC) would like to make a T shirt featuring the four elements plus a schematic of a HOSC molecule. Is there such a thing?
