Hello
How should i calculate number of electrons passing through it
when we apply some gate voltage across it

Is this the article from which you got that image ?
https://en.wikipedia.org/wiki/Bipolar_junction_transistor

Section "Theory and modelling" addresses your question.

in BJT's we call it "Base" not "Gate".

That article should get you started.

Train your search engine. It wants to help you.

Wouldn't you need the amount of time over which the electrons are flowing? Maybe you mean "number of electrons/second"?

Hello
I want to count the number of electron that can flow from it at forward bias of bjt
