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
A
6.5 x 10-2kg
B
2.6 x 10-2kg
C
6.5 x 10-3kg
D
2.6 x 10-3kg
correct option: d
m = QZ
= 2 x 104 x 1.3 x 10-7
= 2.6 x 10-3kg
= 2 x 104 x 1.3 x 10-7
= 2.6 x 10-3kg
