The electrochemical equivalent of a metal is 1.3 x 10-7kgC-1. The mass of the metal which 2.0 x 104C of electricity will deposit from a suitable electrolyte is
- 6.5 x 10-2kg
- 2.6 x 10-2kg
- 6.5 x 10-3kg
-
2.6 x 10-3kg
The correct answer is: D
Explanation
m = QZ= 2 x 104 x 1.3 x 10-7
= 2.6 x 10-3kg
