Chemistry Level pending

An acidic solution of $$Cu^{2+}$$ salt containing 0.4 g of $$Cu^{2+}$$ is electrolysed until all the copper is deposited.The electrolysis is continued for 7 more times with the volume of the solution kept at 100 mL and the current at 1.2 A. Calculate the volume of gases evolved at STP during the entire electrolysis.
