An unknown powder has been found at a crime scene. It is your job to identify the chemical formula for the substance and its common or generic name by searching the internet. Preliminary tests reveal that the possible elements that can be in the material are carbon, hydrogen, oxygen and nitrogen. Complete combustion of a 0.695 g sample of the unknown powder with excess O2 produced 1.2387 g of CO2, 0.5072 g of H2O, and 0 g N2. The molar mass of the substance was found to be about 222 g/mol.
