Given a cell membrane with the following parameters-
Ion Extracellular concentration (mmol/L) Intracellular concentration (mmol/L) Permeability
K⁺ 10 150 1
Na⁺ 140 15 0.04
Cl^- 100 7 0.45
calculate the membrane potential of the cell inmV. (Round your answer to the nearest hundredth.) Assume standardtemperature and pressure.
