Answer: 3. 19300 C
Explanation:
1 electron carry charge=
1 mole of electrons contain= electrons
Thus 1 mole of electrons carry charge=
At cathode:
of electricity deposits 1 mole of copper
1 mole of copper is deposited by = 193000 C
0.1 mole of copper is deposited by =
Thus 19300 C of of electricity that should be passed through CuSO4 solution with Cu electrodes to deposit 0.1 gram atom of Cu.

1 mol of Cu is deposited by 193000 C of electricity
0.1 mol of Cu is deposited by=(193000×0.1)÷1=19300 C of electricity
Final answer is 3. "19300 C"
