delta Go = -431.16kJ/mol - (298k X 0.12529 kJ/K*mol)
I am having trouble converting the units for delta H and delta s to match. I multiplied delta H by 1000 to get kJ but this didn't give me the correct answer.

delta H is usually listed in kJ/mol and S in units of J/mol. Most of the time I want to use dG I must convert it to J so I usually convert delta H to J (1000 x delta H in kJ/mol = delta H in J/mol) and that will match S in J/mol. That will give you dG in J/mol.

I did
-431.16kJ/mol X 1000 = -431160
Then -431160 - (298 X 0.12529 kJ/K*mol) = -431197.33 for delta G but this answer was said to be incorrect, I do not know why??

To convert units, it's important to understand the relationship between the units being converted. In this case, you are trying to convert kJ/mol to J/mol. There is a conversion factor of 1 kJ = 1000 J, meaning that 1 kJ is equivalent to 1000 J.
To convert -431.16 kJ/mol to J/mol, you need to multiply it by the conversion factor of 1000:
-431.16 kJ/mol * 1000 J/kJ = -431160 J/mol
So, the conversion from kJ/mol to J/mol gives you -431160 J/mol.
Similarly, to convert 298 K from kelvin to degree Celsius, you need to subtract 273.15 from it. This conversion will give you the temperature in degrees Celsius.
