1) Under appropriate conditions in an electrolytic cell, the electrolysis of an aqueous solution of copper II sulfate took place. In this process, 6.35 g of copper were formed and a gas was evolved. Data: massa (O)= 16 g/mol; Mass(Cu) = 63.5 g/mol. Cathodic half-reaction: Cu2(aq) + 2e- Cu Anodic half-reaction: 2 H2O O2 + 4e +4H*aq What is the volume of gas produced when measured at STP
