Determine the cell potential (in V) for a platinum electrode in an acidic solution of 0.004M H+(aq), 3.226M ClO4-(aq) and 4.445M ClO3- (aq) ions, coupled to a gold electrode in 3.238 M Au3+ (aq) at 307.10 K.

Im confused about the mulitple molarities given for the platinum electrode. Do i just mutiply them in the Ecell equation?
