Asked by Michelle
I'm having some trouble with a problem on my physics pre-exam, if there is any formula please let me know so i can do a bit of research on it. any help is greatly appreciated in advance.
The inner membrane of a cell membrane is negative relative to the outer surface. if 1.6 X 10^-20 J of work is required to eject a positive sodium ion (Na+) from the interior of the cell, what is the potential difference between the inner and outer surface? Hint: Na+ has one electron deficiency.
