Calculate the potential of the following two half- cells that are connected by a salt bridge: a galvanic cell with two platinum electrodes, the one on the left immersed in a solution that is 0.0301 M in Fe3+ and 0.0760M in Fe2+, the one on the right is a solution that is 0.0309 M in Fe(CN)6 4- and 0.1564 M in Fe(CN)6 3-
