1 The mass and size of the molecules in a liquid and how closely they are packed together determine the density of the liquid. 2  Just like a solid, the density of a liquid equals the mass of the liquid divided by its volume; D = m/v.  The density of water is 1 gram per cubic centimeter.
Answer 2: They are less dense than water. Pure water has a density of 1 gram / cubic centimeter, or 1 gram / milliliter. (1 milliliter = 1 cubic centimeter). When water freezes, it expands into a crystal lattice and its density is less than that of liquid water.
