This table below provides approximate values for the intracellular and extracellular concentrations in unit mmol/L for sodium, potassium, and chlorine ions in a frog muscle with a resting potential difference of -98 mV and for the squid axon with a resting potential difference of -70 mv. Calculate the equilibrium potential difference in mV) for each ion species in both cases at 17°C.
