Answer: 42 hours
Explanation:
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 =
According to stoichiometry:
1 mole of electrons deposit = 23 g of sodium
i.e 96500 C of electricity deposit = 23 g of sodium
Thus 23 g of sodium is deposited by = 96500 C of electricity
of sodium is deposited by = C of electricity
To calculate the time required, we use the equation:
where,
I = current passed =
q = total charge =
t = time in secods = ?
Putting values in above equation, we get:
Thus 42 hours are required.
