Here is your answer
[tex]\bold {1.875 × {10}^{19} electrons} [/tex]
REASON:
We know that
No. of electrons in 1 coulomb charge =[tex] 6.25 × {10}^{18} electrons[/tex]
So,
No. of electrons in 3 coulomb charge=[tex] 3 × 6.25 × {10}^{18} electrons [/tex]
=[tex]18.75× {10}^{18} electrons[/tex]
= [tex]1.875 × {10}^{19} electrons [/tex]
