Not sure if I still know how to do this, but don't you just use product - reactant? Would this help? http://www.chem.tamu.edu/class/majors/tutorialnotefiles/gibbs.htm

but it is not said that it is "standart state", can I still use that temperature (298 K)?

You can look up the standard enthalpy (delta H), and entropy (delta S) values in the back of the chemistry book.
