From the question, we can get that there is only carbon, hydrogen, nitrogen and oxygen in this compound. So if we use the total amount minus weight of carbon, hydrogen and nitrogen, we can get the weight of oxygen. The mass percent equals the mass of oxygen divided by compound mass multiply 100%. The answer is 15.3%
