One form of the equation for the change in Gibb's Free Energy is as follows:
ΔG = ΔGo + RT⋅ln(Q)
The question has given all terms of the equation except ΔGo, so all you have to do is plug in the numbers, convert units as necessary, and then solve for ΔGo.
ΔGo = ΔG – RT⋅ln(Q)
= -126.1 kJ/mol * (1000J / 1kJ) – (8.314 J/mol⋅K * 298K * ln (0.043)
