Calculate the time required to coat a metal surface of `80 cm^(2)` with `0.005 mm` thick layer of silver (density `= 10.5 g cm^(3))` with the passage of `3A` current through silver nitrate solution.

Explanation

To solve the problem of calculating the time required to coat a metal surface of 80 cm² with a 0.005 mm thick layer of silver using a current of 3 A, we will follow these steps:

### Step 1: Convert the thickness from mm to cm
Given thickness = 0.005 mm
To convert mm to cm, we use the conversion factor:
1 mm = 0.1 cm
Thus,
Thickness in cm = 0.005 mm × 0.1 cm/mm = 0.0005 cm
