Answers are in approximate terms. Little variation is not to be minded.

If asked in mole, number of Cu²+liberated will be 96/192000 moles =1/2000 moles =0.0005 moles or 3.011×10^20 Cu²+ ions. My answers perhaps satisfy you

Aakash Kumar 5 years, 3 months ago

Cu²+ +2e=Cu(e=charge carried by one electron) So 2e charge required for liberation of 1 Cu²+. 2 F(1 F=charge carried by one mole of electrons =96500C) Charge required for liberation of 1 mole of Cu2+=63.5g 193000C gives 63.5 g. Here, Q=It=1.6×60C =96C So, mass of Cu²+ liberated=96/193000 ×63.5 g=0.0315 g(approx) Khushi, Please reply whether I am right.
