Answer 1

SI unit of electric charge is Coloumb (C) .
6.24*10^18 electrons make 1 c of charge.

Answer 2

Hi 
______________________________________________________________
SI Unit OF electric charge is Coulomb

As we know ,

q = ne 

1 = n x 1.6 X 10 ^-19 

So, n = 1/1.6 X 10 ^-19 
    
      n = 0.625 x 10^19 
      
     n = 6.25  X 10^18
