The membrane that surrounds a certain type of living cell has a surface area of 7.1 x 10^-9 m² and a thickness of 1.6 x 10^-8m. Assume that the membrane behaves like a parallel plate capacitor and has a dielectric constant of 5.7.

(a) The potential on the outer surface of the membrane is +51.6 mV greater than that on the inside surface. How much charge resides on the outer surface?

(b) If the charge in part (a) is due to K+ ions (charge +e), how many such ions are present on the outer surface?
