A student wants to determine the concentration of silver ions (Ag+) in a solution. Using an Ag/Ag+ reference electrode, the student measures the cell potential to be +0.56 V when the solution is electrolyzed for 25 minutes at a constant current of 0.50 A. The volume of the solution is 150 mL. What is the concentration of silver ions in the solution in mol/L?
