### Question

The electrochemical equivalent of a metal is 0.126 × 10-6 kg/C. The mass of the metal that a current of 5A will deposit from a suitable bath in 1 hour is

A)
0.378 × 10-3kg
B)
0.227 × 10-3kg
C)
2.268 × 10-3kg
D)
0.0378 × 10-3kg

### Explanation:

Note: The electrochemical equivalent, sometimes abbreviated Eq, of a chemical element is the mass of that element transported by 1 coulomb of electric charge. The electrochemical equivalent of an element is measured with a voltameter.

• You guys should not confuse us ooo
Explanation
m = Itz

= 5 x 3600 x 0.126 x 10-6

= 2.268 x 10-3kg

• Nigerian scholars.... The answer is wrong. The correct answer is C... 2.268x10^3, not A. Pls correct it.

Using M= Zit
I= 5A
T= 1hr = 60x60 = 3600s
Z= 0.126x 10–6

M= ZIt
0.126x10-6x 5x3600
M= 2268x 10-6

1. Thank you this really helped

2. $$Z= MIT$$
