What is the empirical formula of a compound that is comprised of 38.65% Carbon, 16.25% Hydrogen, and 45.09% Nitrogen? For your answer simply put subscripts directly after the element's symbol. You do not need to put anything for a subscript of '1'. For example, if your answer is supposed to be 'C2H2N2' then you would input 'C2H2N2'. Your answer should be written Carbon first, Hydrogen second, and Nitrogen third.
