Hello there!
Greetings!
I am extremely sorry to tell you dear but you haven't completed your questions. But I guess the question is asking about the quantity of electricity required to produce the aluminium.
Now,from Faraday's first law ,we know that
W = ZQ
where w = Weight Z = Electrochemical equivalent and Q = Quantity of electricity
Now, E = Z F
where E = equivalent weight and F = faraday
or W = E/FQ
or Q = WF/E
or Q = WF/A/n
Thus, Q = nwf/A
= 35.121096500/27
= 5.49 10 C
Thus, to prepare 5.12 kg of aluminium metal we need 5.49 10 C of electricity
Thankyou
Question : An alloy contains 30 percent aluminium. What quantity of alloy will have 300 grams of aluminium?
Option 1: 0.8 kg
Option 2: 1 kg
Option 3: 1.2 kg
Option 4: 0.6 kg
Question : An alloy is made by mixing metal A, costing Rs. 2000/kg, and metal B, costing Rs. 400/kg, in the ratio A : B = 3 : 1. What is the cost (in Rs.) of 8 kg of this alloy?
Option 1: 1600
Option 2: 9800
Option 3: 6400
Option 4: 12800
