Question

What is the empirical formula of caffeine (C8 H10 N4 O2)?
How do I get it?
Thanks

Answer 1

You look for a number that divide into all of the subscripts evenly. For example, I see that all of the numbers can be divided evenly by 2. I would do that, then see if any other factor can be used. If not, then C4H5N2O will be the empirical formula.
