A hydrometer is an instrument used to measure the specific gravity (or relative density) of liquids; that is, the ratio of the density of the liquid to the density of water.
A hydrometer is usually made of glass and consists of a cylindrical stem and a bulb weighted with Mercury or lead shot to make it float upright. The liquid to be tested is poured into a tall container, often a graduated cylinder, and the hydrometer is gently lowered into the liquid until it floats freely. The point at which the surface of the liquid touches the stem of the hydrometer is noted. Hydrometers usually contain a scale inside the stem, so that the specific gravity can be read directly. A variety of scales exist, and are used depending on the context.
Hydrometers may be calibrated for different uses, such as a lactometer for measuring the density (creaminess) of milk, a saccharometer for measuring the density of sugar in a liquid, or an alcoholometer for measuring higher levels of alcohol in spirits.
What else can I help you with?
Is one cc a measure of density?
1 cc's is a measurement of volume not density. In most cases liquids are measured in cc's. Many liquid medications are to be given in a certain amount of cc's.
Why is the value determined for the metal density likely to have a larger relative error than the value deterimined for the liquid density?
The measurement of the metal's density is likely to have a larger relative error because metals are denser and have higher absolute values compared to liquids. Thus, any small measurement errors will have a proportionally larger impact on the calculated value for the metal density. In contrast, the density of liquids is lower, so the same absolute error will result in a smaller relative error in the calculated value for liquid density.
Is the density of liquids the same as the density of gases?
No, the density of liquids is generally higher than the density of gases. This is because the particles in liquids are closer together and have more intermolecular forces compared to gases. Consequently, liquids have a higher mass per unit volume, resulting in a higher density.
Is true about density and states of matter for most substances?
The density of solid state of matter is higher than the density of liquids and the density of liquids is higher than the density of gases.
What is true about density and states of matter for most substances?
The density of solid state of matter is higher than the density of liquids and the density of liquids is higher than the density of gases.
How can liquids be separated density?
Liquids can be separated by the density difference by centrifugation.

How is a substance's density calculated?
Density is the ratio beween the mass and the volume.Many devices exist in laboratory do determine the density: special analytical balance, pycnometer, helium pycnometer, densimeter (for liquids), electronic densimeter (for liquids) etc.; for perfect geometrical shapes the measurement of dimensions-calculation of volume-weighing are sufficient.
What unit of measurement is used for the density liquids?
To explain first: density is mass (m) per unit volume (V)-how heavy something is compared to its size. Water, for example, has a density of 1g/cm3.
What are some examples of low density liquids and how do they differ from high density liquids?
Low density liquids include substances like gasoline, alcohol, and oil. These liquids have fewer particles packed closely together, resulting in a lower mass per unit volume compared to high density liquids like water or mercury. This means that low density liquids are lighter and less dense, making them float on top of high density liquids.
Why is the value determined for the metal density likely to have a larger relative error than the value deterimined for the liquid density?
The measurement of the metal's density is likely to have a larger relative error because metals are denser and have higher absolute values compared to liquids.

What causes objects to float?
in relation to solids or liquids in liquids: Density. A lighter density compound/liquid will float in a heavier density liquid
What is the use for a beaker?
measurement of liquids
Does a hydrometer measure density?
Hydrometer is the apparatus measuring relative density of the liquid subject in related to water. The output from measurement after multiplied with water density then would give the density.
