How much work is done (by a battery, generator, or some other source of potential difference) in moving avogadro's number of electrons from an initial point where the electric potential is 9.20 v to a point where the electric potential is -5.30 v? (the potential in each case is measured relative to a common reference point.)?

Work done= 1397104 J

Explanation:

Work done= q ΔV

q= charge

ΔV= potential difference

ΔV=-5.3 - 9.2= -14.5 V

q= n e

n= number of electrons= 6.022 x 10²³ ( Avogadro number)

e= charge of electron= -1.6 x 10⁻¹⁹ C

so charge= q= 6.022 x 10²³ (-1.6 x 10⁻¹⁹)=-96352 C

so work done = q ΔV

W= -96352 (-14.5)

W= 1397104 J
