The answer to this question would be: 1 g/cm 3
The density of water should be 1g/cm3. If you want to know how much it is in a milliliter, then you need to convert the cm3 into the milliliters. But the question is about density. The density of water will not be changed if its volume became less. The volume only used to determine the water weight. In this case, 1 milliliter of water will weight: 1ml * 1g/cm3 * 1cm3/ml= 1 gram
