In fuel cell `H_(2) and O_(2)` react to produce electricity. In the process, `H_(2)` gas is oxidised at the anode and `O_(2)` at cathode. If 44.8 litre of `H_(2)` at `25^(@)C` and also pressure reacts in 10 minutes, what is average current produced? If the entire current is used for electro deposition of Cu from `Cu^(2+)`, how many grams of Cu deposited?
