At 37 °C the equilibrium concentration of Ca²+ inside a cell is 0.078 M and outside is 0.04 M. The cell membrane is permeable to Ca²+ and Cl-. The only ion present in addition to Ca²+ and Cl- is a protein (Prin+/-) inside the cell. The protein holds a single positive or negative charge. The CI is at equilibrium across the membrane while the protein is inside the cell and cannot permeate the membrane. What is the concentration of Prin+/- (in M)?
