Adenine is a substituted form of a heterocyclic nitrogenous base Purine. Adenine is found in both polymers DNA and RNA . Adenine is composed of the elements carbon, hydrogen and nitrogen and has molecular mass of 13.5 amu . Upon analysis, it was found that the ratio of % (by w.t. ) of carbon to that of total % (by wt ) of hydrgoen and nitrogen was found to be 4:5 respectively. The ratio of number of N atoms to hydrogen atoms is 1 : 1 . Now, answer the following questions: In one molecule of adenine :
