Nitrobenzene contains 5 hydrogen atoms 6 carbon atoms 2 oxygen atoms and 1 nitrogen atom. what is the chemical formula for nitrobenzene?

To develop the chemical formula of a substance or compound in this regard, one only needs to write the chemical symbol for each of the element present and write as subscript to each symbol the number of atoms of that element. For nitrobenzene, as described above, the chemical formula should be,
                      C₆H₅O₂N

Yeah, but what are you trying to ask?
