Imagine you have built an artificial membrane of​ which there are only sodium channels, then you place the membrane between two chambers containing water. In the OUT chamber, you put 50 mM $NaCl$ in the water; in the IN chamber, you put 5 mM $NaCl$. Then, you let the ions move freely across the artificial membrane until the equilibrium is reached.

Use the approximated Nernst equation: $62\times \log { \cfrac { { \left[ ion \right] }_{ out } }{ { \left[ ion \right] }_{ in } } }$. The membrane potential (mV) at 37$^oC$ is
