Given the values of S^o given below in J/mol K and the values of ΔH_f^o given in kJ/mol, calculate the value of ΔG^o in kJ for the combustion of 1 mole of propane to form carbon dioxide and gaseous water at 298 K.

S (C₃H₈(g)) = 274

S (O₂(g)) = 209

S (CO₂(g)) = 216

S (H₂O(g)) = 181

ΔH_f^o (C₃H₈(g)) = -105

ΔH_f^o (CO₂(g)) = -394

ΔH_f^o (H₂O(g)) = -225
