Answer : It takes time to produce 3 g of aluminium is, 165 seconds.
Explanation :
As we are given that the mass of aluminium is, 3 grams. Now we have to calculate the total mass of aluminum.
Total mass of aluminum = 3g × 24 = 72 g
Now we have to calculate the moles of aluminum.

Molar mass of Al = 27 g/mol

As, 1 mole of Al has 3 Faradays
So, 2.67 mole of Al has =
Faradays
and,
Charge = 
Current = 
Now we have to calculate the time.

Hence, it takes time to produce 3 g of aluminium is, 165 seconds.
