For the following problem, use s separate sheet of paper to solve the problem. Select your answer from the choices given and then upload your solution at the following link: https://canvas.dccc.edu/courses/28465/assignments/575253   Your work must be shown for full credit. The answer alone is only worth 1 point.   A voltaic cell consists of a Mn/Mn2+ electrode (E° = –1.18 V) and a Fe/Fe2+ electrode (E° = –0.44 V). Calculate [Fe2+] if [Mn2+] = 0.050 M and Ecell = 0.78 V at 25°C.
