What voltage should be applied across the cell membrane


Problem: The cell membrane has channel molecules that pass Na+ ions. The Na+ concentration of the extracellular solution is 120 mM and that of the cell interior is 5 mM. What voltage should be applied across the cell membrane at a temperature of 25 C so that Na+ ions do not pass through the channels when the channels are open?
