Finding the volume and comparing it to the mass will give you the density, then it is simply a matter of looking up which materials have that density to find what it is.
And that is how you can tell howthe density can be used
By comparing the measured density to a table of known densities for different substances. Of course, since several substances may have similar densities, it is best to use additional criteria to identify a substance - such as its color for example.
pretty sure this is right but, you can because once you have the density you can use a chart with substances on it then you can match the with the unknown substance. at least that's what we do in my class...i think?
Density is a unique property to every compound. I use unique is a loose manner. It is an indication that the liquid (more well studied than solids densities) is what you think it is. However, many liquids share the same density, so it is by no means conclusive.
i have no clue that's why i jsut asked this question
Each material has a characteristic density in standard conditions of temperature and pressure.
Density is defined as the ratio of an object's mass to its volume.
Since characteristic properties for a given substance never change, they can be used to identify unknown matter.
the pH of the substance
Although Rf values technically remain constant if the following are held constant: * solvent system * adsorbent * thickness of the adsorbent * amount of material spotted * temperature They are generally not used to identify an unknown substance specifically, since these factors are sometimes difficult to control. Most generally, during a chromatography experiment an unknown sample can be compared directly to a known sample simultaneously, i.e. they will have similar Rf values.
The substance may be poisonous.
A lactometer is used to measure the specific gravity (richness) of milk.
So they can determine the density of a substance. Density = mass/volume. Density can be used to identify a substance.
The density of any substance is constant, we don't control it. However, by finding the density of any substance, it can be used to help identify the substance.
Density is a very important property which can be used to identify a substance. We can calculate Density by dividing mass by volume.Density is the measure of how compact something is. To calculate density, take the mass of the substance, and divide it by the volume of the substance.
Density is a Characteristic Property because it is A quality of a substance that never changes and can be used to identify the substances.
Since characteristic properties for a given substance never change, they can be used to identify unknown matter.
Just about any property that can be observed or measured can help you reduce the number of options.

Yes, a dichotomous key is used to identify an unknown organism.
Yes, a dichotomous key is a tool used to help identify unknown organisms by presenting a series of paired characteristics for the user to choose from, ultimately leading to the identification of the organism.
Physical and chemical properties can be used to identify a substance or predict how it will behave.
Yes, it is possible. To identify an object using its density you need only a few things: an accurate scale to find the mass of the object; a graduated cylinder large enough to accommodate whatever object you have; the object itself; and a liquid. Any liquid can be used for this, however, if the object floats then the calculation becomes slightly more complicated. I use water. First weigh the object, then immerse it in the liquid. Note how much water is displaced. Divide the mass of the object by the volume of the liquid and you'll find the density. Then compare that density to the list of known densities to identify the object. Pretty simple! physical and chemical properties can be uesed to identify substance. I used: http://www.ehow.com/how-does_5187289_density-used-identify-substances.html Ans: Not sure you can actually identify the substance from its density alone: you would have to know its state too. For example, water in gaseous form would be an entirely different density to water in solid form wouldn't it? So no, you cannot identify a substance from its density, without other information. The best way to identify a substance is often through spectroscopy, in which the radiation either absorbed or given off from a chemical can determine which substances are present. This is what happens for the sun.
To identify an unknown sample by its emission spectrum
