Explanation: Hope this helps
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%
Both animal and plant cells undergo respiration. Although this respiration goes toward different activities (photosynthesis for plants and muscular respiration for animals), both processes intake oxygen and get rid of carbon dioxide as a waste product.
