Electrochemical cells can be used to measure ionic concentrations. A cell is set up with a pair of Zn electrodes, each immersed in ZnSO4 solution. One solution is created to be exactly 0.500 M, and the potential on its electrode is measured to be 0.075 V higher than the other electrode. What is the concentration of the other solution? Enter your answer in M.
