+1.101V

Explanation:

  1. The 2 ionic half equations of the cell are given below.
    Since zinc is more reactive than copper, zinc loses electrons more readily to form #Zn^(2+)# ions.
    #Zn (s) -> Zn^(2+)(aq) +2e^-#
    #Cu^(2+)(aq) +2e^- -> Cu(s)#
  2. Look up the standard potentials for the half-reactions.
    #E^o# for reduction of #cu^(2+)# is +0.339V
    #E^o# for oxidation of #Zn# is +0.762V

Cell potential
= +0.339V +0.762V
= +1.101V
