Okay. This is the question: If 130.943 g of a liquid occupy a space of 135.0 ml, what is the density of the liquid in g/cm3? And this is my answer: 0.9699481g/ml 481 is repeating

**Math?**

Wait! I'm a bit confused. Let me try and do the problem and you check it for me please?

**Math?**

How do you convert "ml" to grams. 1. 135.0ml to grams
