A `35%` solution of `LiCl` was electrolyzed by using a `2.5 A` current for `0.8 h. ` Assuming the current efficiency of `90%` , find the mass of `LiOH` produced at the end of electrolysis. `(` Atomic mass of `Li=7)`

Explanation

To solve the problem of finding the mass of LiOH produced at the end of electrolysis, we will follow these steps:

### Step 1: Calculate the total charge (Q) passed during electrolysis
The total charge can be calculated using the formula:
\[ Q = I \times t \]
Where:
- \( I \) = current in amperes (A)
- \( t \) = time in seconds (s)
