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
