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 H_2O is a chemical formula for water. There are two Hydrogens (H) and one oxygen (no need for a subscript if there is only one). How many atoms total are in the H_2O_2 molecule?

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 3Fe_2O_3, how many oxygen atoms do I have total?
