The membrane that surrounds a certain type of living cell has a surface area of 6.1 x 10-9 m2 and a thickness of 1.3 x 10-8 m. Assume that the membrane behaves like a parallel plate capacitor and has a dielectric constant of 5.3.

(a) The potential on the outer surface of the membrane is +53.1 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?
