The density of a material is defined as its mass per unit volume.

The density of liquid water is normally given as 1000 kg/m3 or 1 g/cm3 as a very accurate estimate, but often ranges slightly below this value, depending on temperature.

Unlike other agents that tend to freezing point, water tends to expand as at freezes; it therefore becomes less dense. Thus, the density of solid water is normally given as just over 91% of this; a common given value is 9.17 g/cm, or 9170 kg/m3.
