Question

How many mol of electron will have total charge equal to 4816 coulomb

Answer 1

1 mole of any substance has 6.022 x 10^23 particles.

1 electron has 1.6021766208(98)×10−19 coulombs 

Therefore 6.022 x 10^23 electrons will have = 
(6.022 x 10^22) x (1.6021766208×10−19 )coulombs

=   9648.17 coulombs.
If 9648.17 coulombs = 1 mole
Therefore 4816 coulombs= 1 mole x 4816/9648
                                       
  = 0.4992 moles 

Answer 2

for 4816 coulomb =1 mole x 4816/9648

=0.4922moles
