A chemist fills a reaction vessel with 0.623g mercurous chloride(Hg2Cl2) solid, 0.645M mercury (I) (Hg2^2+)aqueous solution, and 0.905M chloride (Cl-) aqueous solution at a temperature of 25.0°C.

Under these conditions, calculate the reaction free energy ΔG for the following chemical reaction:
Hg2Cl2(s) ⇌ Hg2^2+ (aq) + 2Cl^- (aq)
