I realize it varries substancially based on what kind of ore is in it, but I was just wondering what an average might look like.

Typically about 3.3 grams per cubic cm for the common rocky asteroids. Anything significantly less is probably not a solid body but more likely a loose aggregate. Up to around 7.9 grams per cubic cm for the rarer solid iron-nickle asteroids.
