A galvanic cell was constructed with a nickel electrode that

A galvanic cell was constructed with a nickel electrode that was dipped into 1.6 M NISO4 solution and a chromium electrode that was immersed into a solution containing Cr3+ at an unknown concentration. The potential of the cell was measured to be 0.501 V, with the chromium serving as the anode. The standard cell potential for this system was determined to be 0.487 V. What was the concentration of Cr3+ in the solution of unknown concentration? [Cr3+] = __________
