3Cu+ (ag) + Au3+ (aq)->3Cu²+(aq) + Au(s) A student studying

3Cu+ (ag) + Au3+ (aq)->3Cu²+(aq) + Au(s) A student studying the reaction represented above constructs a voltaic cell as shown in the diagram below. The cell contains an Au(s) electrode in a beaker containing 1.00 M Au(NO3)3(aq) and a Pt(s) electrode in a beaker containing 1.00 M CUNO3(aq) and 1.00 M Cu(NO3)2(aq). The standard reduction potentials associated with the cell are given in the following table. Half-reaction E° (V) Cu²+ (aq) + e→ Cu+ (aq) 0.16 Au³+ (aq) + 3 e → Au(s) 1.50 a. Calculate the value of the standard cell potential, E. b. Does the mass of the Pt(s) electrode increase, decrease, or remain the same as the cell operates? Justify your answer.
