Consider a Voltaic Cell That Operates from the Following Redox

Consider a voltaic cell that operates from the following redox reaction:
Mn (s) + Ag¹⁺ (aq) →Mn²⁺ (aq) + Ag (s) What is the value of E ° _cell if E ° _red(Ag¹⁺/Ag) = 0.80 V and E ° _red(Mn²⁺/Mn) = - 1.18 V?

A) E ° _cell = - 1.98 V
B) E ° _cell = - 0.94 V
C) E ° _cell = - 0.38 V
D) E ° _cell = 0.38 V
E) E ° _cell = 1.98 V
