When a current of 1.5 amp was passed for 30 minutes through a solution of a salt of a trivalent metal, 1.071 g of the metal was deposited at the cathode. Calculate the atomic weight of the metal.

Explanation

To calculate the atomic weight of the trivalent metal deposited during electrolysis, we can follow these steps:

### Step 1: Understand the Given Data
- Current (I) = 1.5 A
- Time (t) = 30 minutes = 30 × 60 = 1800 seconds
- Mass of metal deposited (w) = 1.071 g
- The metal is trivalent, so n-factor (valency) = 3.
