I talk to my friend about language. I tell her about who whom. I tried to explain to her that whom could be for objects/If you can ask a question/answer it with him/her. She asked me which would she use here: “Would you tell me the number of whom wrote this paper?”. I did not know how to explain to her which one to use. Which would work here?: “Would you tell me the number of whom wrote this paper?
Your friend asked a good question.
The meaning of the sentence is
Would you tell me the number of the person who wrote this paper.
It is the role of the pronoun in the subordinate clause that determines the distinction between “who” and “whom.”
Would you tell me the name of who hit Jane
Would you tell me the name of whom Jane it.
