A chemical formula for an molecule will tell you a couple things. To start with - it will tell you have types of atoms are in the molecule. To do this it will use each type of atom's chemical symbol. There will also be a subscript number that will tell you how many of that atom there will be. So
Sometimes you will see a number in front of a chemical formula. Like this -
that just tells me you have three of the same kind of molecule. If I have
