calculate the change in enthalpy when 1.00g of hydrogen peroxide decomposes. H2O2(l) yields H2O(l)+ 1/2O2(g) (traingle)H- -98.2kj

I will be happy to critique your thinking on this.

help me?

You know the delta H is for one mole decomposition. So figure the fraction of 1gram/one mole of H2O2, and multiply that by the delta H given.
