hydronium ion and hydrogen ion?
what's the relationship between hydronium ion (H3 O+) and hydrogen ion (H+)? Is there any mathematical equation for it? Was it inversely something?

Hydrogen ions don't exist "by themselves" in aqueous solution. H+ is charged and therefore will be attracted to the negative end of a water molecule. Back in 1923 Bronsted and Lowry both published papers on acids and bases and both came to the conclusion that aqueous hydrogen ions must be attached to a water molecule, the hydronium ion, H3O+. So the hydronium ion is a more accurate way of depicting a hydrogen ion in water.
Here's something you can use to impress your teacher. Some chemists believe that instead of one water molecule, a hydrogen ion is surrounded by four water molecules all acting as a unit. So a hydronium ion could be H9O4+.

Hydrogen ion really is just hydronium ion in the case of dissociation of water.
H2O-> H+ +OH-
2H2O-> (H3O+) + (OH-)

Yup, hydronium ion.

You have to know that hydronium ion and hydrogen ion can be used to find pH.
2H20-> H3O+ + OH-
and [OH-]+[H] always = 10^-14
