Answer
See explanation below.
Work Step by Step
The reaction is:
Mg2+ + 2 e- --> Mg
a. No of moles of electrons produced is:(35.6 g Mg) (1 mol Mg / 24.31 g Mg) (2 mol e-/ 1 mol Mg) = 2.92883587 = 2.93 mol e-
b (2.92883587 mol e-) (96485 C / mol e-) = 2.83 x 105 coulombs
c (2.83 x 10^5/ 2.5 hr)(1h/3600 sec)= 31.4 A
