Question on: JAMB Chemistry - 1990
0.1 faraday of electricity deposited 2.95 g of nickel during electrolysis of an aqueous solution.
Calculate the number of moles of nickel that will be deposited by 0.4 faraday?
(Ni = 58.7)
A
0.20
B
0.30
C
0.04
D
5.87
Ask EduPadi AI for a detailed answer
Correct Option: A
0.1F ↔ 2.95 g Ni = 0.4F ↔ 11.8 g Ni
No of moles = (11.8)/(58.2) = 0.20 moles
