A very common instrument for the direct measurement of the density of a liquid is the hydrometer, which measures the volume displaced by an object of known mass. A common laboratory device for measuring fluid density is apycnometer; a related device for measuring the absolute density of a solid is a gas pycnometer. Another instrument used to determine the density of a liquidor a gas is the digital density meter - based on the oscillating U-tube principle.
Density is a measure of how tightly the matter within it is packed together.
Hydrometer is used in batteries to measure density. A float tells you the density using displacement.
A densitometer is used in photographic work measure the optical density of a photograph. It can be used to measure both reflective and transparent material.
volume isn't used to measure mass. Except possibly in a roundabout way. If you know the density of a substance, you can use that as a comparison.
The specific gravity of a substance is the ratio of te density of the substance to the density of water. It is, therefore, a unitless measure.
Hydrometer measure the density of liquids.

It is not used for this.A hydrometer is an instrument used to measure the specific gravity (or relative density) of liquids, NOT rock.To measure the density of a rock you weigh a piece of it in air, then measure the volume of water it displaces in a measuring jug.Density = mass/volume.
Graphing is used in measuring density. It plots the temperature and density as read, and gives the true density at standard conditions.
A hydrometer can be used to find the specific gravity (relative density) of a liquid by determining how much water it will displace. Various calibrations are used for different kinds of liquids.
density -------- Graduated cyllinders are used to measure volumes of liquids, powders or fine granules.
So they can determine the density of a substance. Density = mass/volume. Density can be used to identify a substance.
A densitometer is used in photographic work measure the optical density of a photograph. It can be used to measure both reflective and transparent material.
hygrometer used to measure density of relative humidity in air by using a sensory element such as a hair
It is called a hydrometer.Also, density equals mass divided by volume.See the Related Questions to the left for more information about hydrometer and density.yup
