Change of G value is 209.3 kj/mol

Prove the listed value, the calculated value using Gf and the calculated value using Hf and Sf values agree for the following molecules. points each for G,H,S points for calculating G using G=HTS points for commenting on if the numbers all agree or if there is any difference between using G=HTS versus using G=nGf( products )nGf( reactants )
