Is there a way to know dentate/mono/bi if you're just given the formula? like CN-?

You must do two things to answer this. First you must identify all lone pairs available to behave as Lewis bases. Then you must evaluate whether these lone pairs are spaced far enough from one another (usually two carbon atoms away from one another) in order to span the distances around the Lewis acid metal center. Lone pairs that match these criteria become sites where coordination bonds can form and you can count and assign mono, di, tri, etc.
