Assume three mol H+ must be translocated to synthesize one mol ATP as described in part B above. Given the following steady-state concentrations: ATP = 3.40 mM and Pi = 5.50 mM, the membrane potential Δψ = 168 mV (inside negative), and the pH values in part A, calculate the steady-state concentration of ADP at 37∘C when ΔG = −11.7 kJ/mol.

Express your answer to three significant figures and include the appropriate units.
