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.
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
How do you find the density of an unknown mineral?
To find the density of an unknown mineral, you can measure its mass using a scale and then measure its volume by displacement in water. Divide the mass by the volume to calculate the density of the mineral.
How can you find the density of an unknown liquid?
To find the density of an unknown liquid, you can measure its mass using a scale and then measure its volume by using a graduated cylinder or displacement method. Divide the mass by the volume to calculate the density of the liquid.
What properties do scientists look for to identify an unknown substance?
Scientists look for properties such as density, boiling point, melting point, solubility, conductivity, and reactivity to help identify an unknown substance. By comparing these properties to known data in a database, scientists can often determine the identity of the unknown substance.
What is the procedure to calculate the density of an unknown substance?
divide mass and volume(:
Why is it not necessary to know the volume of a substance when calculating its density?
If you want to CALCULATE the density of an unknown substance, you need to divide its mass by its volume, so you need to measure both first. If it is a homogeneous (uniform) substance, and you can take away a piece, you can take any sample. Any piece of the substance will have the same density.

An 8.192-mL sample of an unknown has a mass of 9.02gWhat is the density of the unknown?
Density is equal to mass divided by volume. In this case, the mass is 9.02g and the volume is 8.192mL. Calculate the density by dividing the mass by the volume: 9.02g / 8.192mL = 1.10 g/mL. So, the density of the unknown substance is 1.10 g/mL.
What procedures would you do if you wanted to calculate the density of an unknown substance?
This depends on the nature and form of the sample:- for a solid with a regulate shape weight the sample and calculate the volume from the dimensions; density is the ratio between mass and volume. You can measure the volume of great sample by water displacement.- for other solids use a pycnometer- for liquids use a densimeter (simple or electronic)etc.
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...
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
What is the density of a rock that has a mass of 56 grams?
The density of the rock is calculated by dividing its mass (56 grams) by its volume. If the volume is unknown, then the density cannot be determined. Density is the mass per unit volume of a substance, so both mass and volume need to be known to calculate it.
How do you find the density of an unknown mineral?
To find the density of an unknown mineral, you can measure its mass using a scale and then measure its volume by displacement in water. Divide the mass by the volume to calculate the density of the mineral.
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 are the usefulness of density in identification of unknown substance?
Density is useful for identifying an unknown material because it is a physical constant. A physical constant is a unique characteristic of the material in question. This constant never change or vary with the shape or amount of the material/substance.
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
