What is 15ml in grams?

Im trying to measure tomato puree if that's any help. I want know how much 1 tablespoon of tomato (which is equal to approx.15ml) puree would cost from a tube of 200g. At 59c i know the answer will be quite small but i really need to know. If you could help my in just how many milliliters are in a gram I would really appreciate it.
