1. The problem statement, all variables and given/known data a biological cell is immersed in a 50mM solution of NaCl at 37C. the cell's membrane is permeable only to Na+ ions. When the system reaches equilibrium, a potential diff of 54.9mV is measured between the inside and the outside of the cell where the inside has the higher( more positive potential. Calculate [Na+] inside the cell, assuming the amount of Na+ ions transferred is negligible compared to the total amoiunt of Na+ ions in the solution. Can anyone tell me where to start?
