0.2864 of Cu was deposited on passage of a current of 0.5 ampere for 30 minutes through a solution of copper sulphate. What is the electrochemical equivalent of copper ? `" (1 F = 96500 coulombs)"`

Explanation

To find the electrochemical equivalent (E) of copper, we can use the formula:

\[ E = \frac{m}{Q} \]

where:
- \( E \) is the electrochemical equivalent,
- \( m \) is the mass of the substance deposited (in grams),
- \( Q \) is the total electric charge passed (in coulombs).
