Answer 1

Answer:

hope the answer will help you

Answer 2

Answer:

Total charge = 4320 C

moles of electron ≈ 0.0448 moles.

Explanation:

Since Q = i × t

Q = 0.4 × 3 × 60 × 60 Coulombs

Q = 4320 Coulombs.

Now, since one mole of electron carries a charge equal to 1 Faraday (≈96485 C)

So, total moles of electrons passing through the filament during this time will be

n =  $\frac{4320}{96485}$  moles

n ≈ 0.0448 moles.
