An alien cell membrane at 41.000°C is found to be permeable to Al³+ but not to anions, and analysis shows the inside concentration to be 0.350 M and the outside concentration to be 0.046 M in Al³+. Assuming the activity coefficients are equal to 1, what is the potential difference in volts across the membrane using the potential within the cell with respect to outside the cell?
