Potential in a different kind of cell.   A typical mammalian cell at 37 ∘C, with only potassium channels open, will have the following equilibrium: K+ (intracellular)   ⇌  K+ (extracellular), with an intracellular concentration of 150 mM K+, and 4.0 mM K+ in the extracellular fluid. What is the potential, in volts, across this cell membrane?  Note: in this case, n = the charge on the ion, and Eo for a concentration cell = 0.00 V.
