Question
Police officers confiscate a packet of white powder that they believe contains heroin. Purification by a forensic chemist yields a 39.69 mg sample for airproof combustion analysis. The sample gives 99.96 mg of CO2 and 21.34 mg of H20. A second sample is analyzed for nitrogen content, which is 3.8%. What is the empirical formula of the compound? List the elements in standard order for carbon compounds: C followed by H followed by other elements in increasing atomic number. Formula: 2 Edit The formula for heroin is C21H23NO5. Select the best response that characterizes these results: the white powder does not contain heroin because the formulas do not match. the white powder could contain heroin because the formulas match closely enough. no conclusions can be drawn because there is insufficient information. the white powder must contain heroin because the formulas match. O O O 0
