Answer: moles
Explanation:
We are given:
Moles of electron = 1 mole
According to mole concept:
1 mole of an atom contains number of particles.
We know that:
Charge on 1 electron =
Charge on 1 mole of electrons =
The metal being plated has a +4 charge, thus the equation will be:
of electricity deposits = 1 mole of metal
Thus 861.8 C of electricity deposits = moles of metal
Thus moles of metal should be plated
