A current of 2A was passed for 1.5 hours through a solution of `CuSO_(4)` when 1.6g of copper was deposited. Calculate percentage current efficiency.

Explanation

To calculate the percentage current efficiency of the electrolysis process where a current of 2A was passed for 1.5 hours through a solution of CuSO₄, resulting in the deposition of 1.6g of copper, we can follow these steps:

### Step 1: Calculate the total charge (Q) passed through the solution.
The formula for charge is given by:
\[ Q = I \times t \]
where:
- \( I \) = current in amperes (A)
- \( t \) = time in seconds (s)
