I'm a bit confused

5. Electrolysis
a) A proposed battery involves the reaction of Zn(s) and Cl2(g) to give ZnCl2. If you want such a
battery to operate for 10 hours and deliver 1.5A current, what is the minimum mass of zinc that
the anode must have?
b) A commercial cell for producing F2 operates at a current of 1500A from the electrolysis of HF
dissolved in KE.
2HF (KF) -
----> H2(g) + F2(g)
How long would this cell have to run in order to produce 25 kg of F2?
c) A solution containing Pt4+ is electrolyzed with a current of 4.00 A. how long will it take to
plate out all of the platinum in 0.50L of a 0.010M solution of Pt4+?
