Using the Nernst equation, calculate the equilibrium potential for the sodium ion if the concentration of sodium outside is 130 mM, and the concentration of sodium in the cytoplasm is 12 mM. Show your work.”

I do not necessarily require the answer (though it would be helpful to know if I do it right), but step by step on how to set this up would be helpful. Would the equation be the same in the situation of potassium (given different numbers of course). Or would something change for that?

Thank you.

In a study concerned with the possible effects of air pollution on the development of chronic bronchitis, the following data were obtained: A population of 9000 men, aged 45 years, was examined in January 1990. Of these men, 6000 were exposed to high levels of air pollution and 3000 were exposed to low levels of air pollution.

At the physical examination, 90 cases of chronic bronchitis were identified, including 60 cases among the high air pollution exposure group.

All of the men who were initially examined and did not have chronic bronchitis were followed by repeat examinations over the next five years. These follow-up exams identified 268 new cases of bronchitis in the total group, including 30 cases among the low-exposure group.

6. The prevalence rates of chronic bronchitis in January 1990 were (Show, your work for all groups):
