An electrochemical cell has copper electrode in 0.250L solution of 0.100M CuSO4 and a silver electrode
in 0.25L solution of 0.100M AgNO3. And the solution is connected by two salt bridges. After an
average current flow of 1.0A for 12min, what will be the volume of the solution of CuSO4? Multiply
your answer by 100 and write the number in the nearest integer. (1mol electron's charge = 96485C)
