The Importance of Chemical Formulas

Chemical formulas tell us the way atoms are put together. The key thing to realize is that compounds or molecules always comprised of whole number ratios of atoms. So for example we have H2O which means two hydrogen atoms bonded to one oxygen atom. And that's just a very simple chemical formula if you get into organic chemistry and look up chemicals perhaps on your bathroom products, some of these things are ridiculously long and complicated so H2O and CO2 are just some very simple examples of that.
