How can the properties of matter identify an unknown substance?
The properties of matter, such as physical characteristics (melting point, boiling point, density, solubility) and chemical properties (reactivity, pH, combustion), can help identify an unknown substance by providing a unique profile. By comparing these measured properties to known standards or databases, one can match the unknown substance to a specific compound. Additionally, techniques like spectroscopy and chromatography can further refine identification by revealing molecular structures and compositions. Overall, a systematic analysis of both physical and chemical properties allows for accurate identification of unknown substances.
What is the procedure to calculate the density of an unknown substance?
divide mass and volume(:
What is the density of an unkown substance that has a volume of 23.0 ml and a mas of 47.5g?
Density is mass/volume.Density of the unknown substance = 47.5g/23.0mL = 2.07g/mLHint: Mass is always measured in grams of some sort; mg, g, kg, etc... Volume is measured in mL, L, m3, cm3, etc...
What physical property is most useful in identifying a unknown substance?
The most useful physical property for identifying an unknown substance is its melting point. This property is characteristic of a substance and can help distinguish it from others, as pure substances have specific melting points. Additionally, comparing the melting point of the unknown with known values can provide a quick and reliable identification method. Other useful physical properties may include boiling point, density, and solubility, but melting point is often the most definitive.
Where you can get a FREE lab type identification on unknown substance read my profile for more information?
I am unable to read your profile, so I cannot access the information you are speaking of. If you are looking for identification of an unknown substance, I recommend taking it to your local police department so it can be identified and then disposed of if it is dangerous.
Can density be used as identification for substances in lab?
Yes, density can be used as a useful property for identifying substances in lab experiments. By measuring the density of a substance and comparing it to known values, scientists can help determine the identity of an unknown substance.
How can density be used to determine the identity of a substancce?
Density can be used to determine the identity of a substance by comparing the density of the unknown substance to the known densities of different substances. Each substance has a characteristic density, so if the density of the unknown substance matches that of a known substance, it can help identify the unknown substance.

What is the procedure to calculate the density of an unknown substance?
divide mass and volume(:
What procedures would you follow if you wanted to calculate the density of an unknown substance?
To calculate the density of an unknown substance, first measure its mass using a balance. Then, determine its volume by either measuring its dimensions and calculating the volume or using displacement method in a liquid. Finally, divide the mass by the volume to calculate the density of the unknown substance.

How can one test an unknown substance to identify it?
To identify an unknown substance, one can conduct tests such as spectroscopy, chromatography, and chemical reactions to determine its properties and composition. These tests can help determine the substance's characteristics and compare them to known substances for identification.
How do you determine the identity of an unknown substance by observing its mass and volume?
All you can do with mass and volume is to determine the density of the substance. density = mass / volume or p=m/v after you determine the density, you can look on any density table and find the substance you are looking for. good look. -julio
What is the density of a 26.5mL sample of an unknown substance that has a mass of 43.54g?
density = mass/volume = 43.54g / 26.5ml ≈ 1.643 g/ml
A 30ml sample of an unknown liquid has a mass off 100g what is the density?
Density is calculated by dividing the mass of a substance by its volume. In this case, the density of the unknown liquid is 100 g / 30 ml = 3.33 g/ml.
How can density be used to identify an unknown substance?
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
If a cubic box is filled with an 44.4g of an unknown substance then what is the density in g per m³ of that unknown substance assuming the box is completely full?
To answer that you would need to know the size (volume) of the box.
