"which one of" v.s. "who of"

[Lost_Soul]

Hi, everybody !

I know that I can say "which one of you knows this rule" (can't I?)

But can I say "Which one of begginers knows this rule"? (a general statement - I am not talking about any particular persons)
Or "Who of begginers knows this rule"?

Thank you

Hi,

My feeling is that you need to have a particular subject in mind to make the sentences sound better. Along these lines:

Which one of you beginners/of you here/of those who are beginners...?

Or

Who of the beginners in the class ...?

Note the spelling: begin/beginner
