(two words, ANSWER IN ALL CAPS)

One half-cell in a voltaic cell is constructed from a copper wire dipped into a 4.8 x 10 ^-3 M Solution of Cu(NO₃)₂. The other half-cell consist of zinc electrode in a 0.40 M Solution Zn(NO₃)_2. Calculate the Cell potential.

Cu²⁺(aq) (4.8 x 10 ^-3 M) + 2e^- ---> Cu(s), if [E^ored=0.337 V]

Zn²⁺(aq) (0.40 M) + 2e^- ---> Zn(s), if [E^ored= - 0.763 V]
