Answer 1

Answer:

1.875×10^19 electrons

Explanation:

We know that Q=ne. ..(1)

where Q= charge

n= no. of electrons

e= charge on 1 electron

Given, Q=3

e= 1.6×10^-19 coulombs

n= ?

putting the values in equation 1, we get

=> 3=n×1.6×10^-19

=> 3/1.6×10^-19

=> 3×10^19/1.6

=> 1.875×10^19 electrons

n=1.875×10^19 electrons ,therefore 1.875×10^19 electrons constitute 3 coulomb of charge
