Knowing the solubility of an unknown substance in water can help you calculate its molarity. It is however important to get its weight first.

Why are solubility tests helpful to determine unknown substances?
A simple solubility test can be used to identify an unknown substance. Most substance will make a precipitate when around certain molecules.
Why is it important to identify an unknown substance?
Because the substance could potentially be extremely toxic or harmful. You must never use an unknown substance in experiments without identifying it first, many tests can be undertaken to determine the cation and anion. These tests include the flame test, solubility tests, precipitate reaction tests and conductivity tests. These do vary depending on the unknown substance.
Name several properties of matter that help you identify an unknown substance?
Every thing
What is meant by a characteristic property of a substance?
Since characteristic properties for a given substance never change, they can be used to identify unknown matter.
Why characteristic properties can be used to identify unknown substance?
- color - odor - taste (if it is possible) - crystalline structure - density - hardness - refractive index - color in the flame - phase of matter - solubility in water and other solvents - reaction with acids and bases - pH (when is possible) and many others
Why Do You Think Scientists Can Use The Basic Properties Of Matter To Help Identify An Unknown Substance?
Because if a substance can't be known then it has to prove its mass and volume
What can be used to identify an unknown substance?
Just about any property that can be observed or measured can help you reduce the number of options.

If you had an unknown substance and were asked to identify it would you use the intensive or extensive properties of the substance?
Intensive properties are independent from the mass of an object: density, hardness, melting point.
How do forensic scientists analyze unknown powders?
Forensic labs are often called in to identify unknown powders, liquids and pills that may be illicit drugs. There are basically two categories of forensic tests used to analyze drugs and other unknown substances: Presumptive tests (such as color tests) give only an indication of which type of substance is present -- but they can't specifically identify the substance. Confirmatory tests (such as gas chromatography/mass spectrometry) are more specific and can determine the precise identity of the substance.
What is important of melting point?
Knowing the melting point of a substance provides information to determine what the substance is if its unknown. If you are making a substance, checking the melting point will let you know if you have made what you set out to make, (because impurities can mess up the melting point)
What is a flame tested used for?
To identify an unknown sample by its emission spectrum
