A biological cell is immersed in a 60. mM solution of NaCl at37°C. The cell's membrane is permeable only to Na+ions. When the system reaches equilibrium, a potential differenceof 82.9 mV is measured between the inside and the outside of thecell, where the inside has the higher (more positive) potential.Calculate [Na+] inside the cell, assuming the amount ofNa+ ions transferred is negligible compared to the totalamount of Na+ ions in the solution.
