A potential difference exists between the inner and outer surfaces of the membrane of a cell. The inner surface is negative relative to the outer surface. If 1.15 × 10-2⁰ J of work is required to eject a positive sodium ion (Na*) from the interior of the cell, what is the magnitude of the potential difference between the inner and outer surfaces of the cell?
