Answer 2

Answer :-

____________________________

2 moles of electrons produce 1 mole of
copper thus the moles of copper
deposited are:

0060435 /2 0.030218 moles

Mass of copper deposited moles of
copper atomic mass of copper.

Atomic mass of copper 63.5g

63.5x 0030218 = 1.9182g

We first write the electrode equation
for deposit of copper at the cathode.

Cu2+ + 2e==>Cus

This implies that 2 moles of electrons
produce one mole of copper.

Given time and current we can
calculate the charge of the electrons:

Qit where Q is the charge in
Coulombs, I is the current in amperes
and t the time in seconds.

Q is thus: 60 60 x 1623600

1.62=5832 Coulombs.
1 mol of an electron 96500 Coulombs
5832/96500=0.040435moles
