Hey friendzz ^___^.
plez ...☺answer this question (2.38).

Answer 1

No. of electron in 2.5× 10^-16 C of charge
==================================☆

As we know that,

One electron contains amount of charge = 1.6× (10)^-19 C

So,

1.6× (10)^-19 C of charge carried out by = 1 electron

thus,

One coulomb of charge is carried out by

= 1/1.6× (10)^-19 electron

So,

2.5×(10)^-16 C of charge carried out by = {1/1.6× (10)^-19}×{ 2.5×(10)^-16} electrons


= 6.25× 10^18 × 2.5× 10^-16 electron

= 15.625× 10^2 electron

= 1.5625 × 10^3 electron are contained.
