If you're trying to calculate the density of a liquid, you also can do so by using an instrument known as a hydrometer. Water's density changes depending on the temperature, so if you're doing an experiment close to or past water's boiling or freezing point, you'll need to use a different value to take into account the change in density. 983.8. Density is just the weight for a chosen amount (volume) of the material. If you're not still in school, then you probably forgot you ever even heard it. The density of liquid water is approximately 1.0 g/mL. As the temperature of warm water decreases, the water molecules slow down and the density increases.

Density is the ratio of the mass to the volume of a substance: = m/V [1], where = density, units typically [g/cm3] or [lb/ft3]m = mass, units typically [g] or [lb]V = volume, units typically [cm3] or [ft3]. Example 1: Specific weight of waterIn the SI system, specific weight of water at 4C will be: = 1000 [kg/m3] * 9.807 [m/s2] = 9807 [kg/(m2 s2)] = 9807 [N/m3] = 9.807 [kN/m3]. You may not know how that affects you, but the specific heat of water has a huge role to play in the Earth's climate and helps determine the habitability of many places around the globe. The density of ice is about 90 percent that of water, but that can vary because ice can contain air, too. The density of water at 21 degrees C is 0.997992 g/mL.
