How long would it take to produce enough aluminum to make a case (24 cans) of aluminum soft drink cans if each can used 3 g of aluminum, a current of 5.00 x 104 A was employed, and the current efficiency was 93.9 %?

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.
