Hey sisy !!!!!!

here is your required answer- (2)

the reaction at cathode is

Al ( 3+) + 3e---------->Al. (n=3)

→applying the equation

w = E×i×t/F

by substituting the values

♦ i × t =
13.5 /(27/3)×F

=13.5/9 ×F

=1.5 F

I hope this will help u ;)

Al 3+ + 3e ----------> Al

1 mole of Al ---- 27

13.5 is given -- which is 0.5 mole

1 Faraday = 1 mole of electrons

1 mole ----------- 30 faraday
0.5 mole ---------- ?

0.5 x 30

= 1.5 faraday
