A potential difference of 90mV exists betwen the inner andouter surface of a cel

Question

A potential difference of 90mV exists betwen the inner andouter surface of a cell membranne. The inner surface is negativerelative to the outer surface. How much work is required to toeject a positive sodium ion from the interior of the cell? This is what i have so far, is this correct? W=qV W=(1.60x10^-19C)(90x10^-3V) W=1.44x10^-20 A potential difference of 90mV exists betwen the inner andouter surface of a cell membranne. The inner surface is negativerelative to the outer surface.

Explanation / Answer

A potentialdifference of 90mV exists between the inner and outer surface of a cell membrane. The inner surface is negativerelative to the outer surface. How much work is required to to eject a positive sodium ion from the interior of thecell? W = Q*(V) = (1.602e-19 C)*(90.0e-3V) =                = 1.442e-20 Joules (
