Electrolysis of molten MgCl2 is the final production step in

Electrolysis of molten MgCl₂ is the final production step in the isolation of magnesium from seawater by the Dow process. If 58.6 g of Mg are obtained, how many amps are required if electrolysis is performed for 9.34 hours?

Solution

m = (i x t)/F x ( M/z)

Mg2+ ---> Mg , z= 2,

58.6 = (9.34x3600x i)/(96485) x (24.3/2)

i = 13.84 amps
