The following half-reactions are used in the zinc-air battery.
(aq) + 2 e-→ Zn(s) + 4 OH-(aq) E° = -1.199 V  
O2(g) + 2 H2O(l) + 4 e-→ 4 OH-(aq) E° = +0.401 V

How much charge is transferred per gram Zn(s) in this voltaic cell?
◦ 5.90 × 103 C
◦ 2.95 × 103 C
◦ 1.47 × 103 C
◦ 3.39 × 10-4 C
◦ 1.69 × 10-4 C
