Answer» 0.07 M 0.2 N 0.005 N 0.02 N Solution :`Q=IxxT` `=1Axx965s=965 C` `Cu^(2+)+UNDERSET(2xx96500 C)(2e^(-))to underset(1 "MOL")(Cu)` `2 xx 96500 C `deposit COPPER = 1 mol 965 C deposite copper `=5xx10^(-3)` mol `therefore` One litre of `CuCl_(2)` solution CONTAIN `=5xx10^(-3)` mol of solute `therefore` Molarity of solution =0.005 M
