The electrochemical equivalent of magnesium is 0.126 mg/C. A current of 5 A is passed in a suitable solution for 1 h. The mass of magnesium deposited will be
A) 0.0378 g
B) 0.227 g
C) 0.378 g
D) 2.27g
Correct Answer:
D
Solution :
Mass m = Zit \[=0.126\times {{10}^{-3}}\times 5\times 3600\] \[=2.27g\]
