Question

) Consider a two-compartment model of a cell with a K+ and Na+ permeable membrane.
The membrane is 1000 times more permeable to K+ than Na+; the concentration of K+ in the
inside compartment is 99.8 mM; concentration of K+ in the outside compartment is 0.5 mM;
the concentration of Na+ in the inside compartment is 200 mM, resulting in a membrane
potential (Vm) of -116 mV. If the membrane now becomes permeable only to Na+ then,
what would be the membrane potential (Vm)?
