Determine the numbers of water molecules are consumed

Question

This battery uses the following half-reactions and has an E° cell value of 1.37 V at25°C. The nickel-iron battery has an iron anode, an NiO(OH)cathode, and a KOH electrolyte.
Fe(s) + 2OH^-(aq) → Fe(OH)₂(s) + 2e- and   NiO (OH)(s) + H₂O(l) + e- → Ni(OH)₂(s) + OH^-(aq)

1.Determine the numbers of grams of Fe(OH)₂ are produced at the anode when the battery produces a constant current of the 0.250 A for 40.0 min?

2. Determine the numbers of water molecules are consumed in the process?
