If you have a mixture of two substances one with a higer density than the other how could you separate the substances in the mixture?

Density is defined as mass per unit volume of a fluid. Therefore, if you compare the same volume of two fluids, the one with higher mass is more dense.
Experimentally, you could take (say 5 mL) of each fluid and weigh each on a mass scale. The the one that weighs more is more dense.
you can also...
~put the liquids in beakers (same amount in both)
~get a marble
~drop the marble in one of the beakers
~use a timer to time how long it takes the marble to reach the bottom of the beaker.
~take the marble out or if you have another marble use that one for the next fluid
~drop the marble into the second fluid
~time how long it takes to reach the bottom
~the fluid with the less time should be the one that is denser
( you don't have to use marbles, you can use any other two object that are and weight the same).

How do properties help us identify substances?
If you wish to separate the constituents of a mixture, knowledge of the properties the constituent substances will help you figure out how to go about separating them. If you have any property (solubility in water, for example) that applies to at least one of you substances, and doesn't to another, you can use the property to separate them. If you wish to separate a solution, knowing the solubility curves of each solute will allow you to separate by changing the temperature. For example, Potassium nitrate has a much higher solubility in water than sodium chloride at high temperatures, but at or near zero degrees Celsius, it has much less. So, if you had a solution of sodium chloride and potassium nitrate, you could lower the temperature drastically and most of the potassium nitrate will precipitate. This is but one example. If you have a solid mixture, and a certain number of the substances in it will dissolve in water (or any other solvent), washing the mixture with the solvent will dissolve those, leaving everything else behind (you could filter the solvent out to separate the substances which don't dissolve) If your substances are physically different in size, you could pass the mixture through a sieve (for example, to separate sand and gravel). If one of your substances is magnetic, but others aren't, you could use a magnet to separate them.
If you have a mixture made of two substances one with a higher density than the other how could you separate the substances in a mixture?
Winnowing. Run the powder through a sifting grid, and allow it to fall into a box below. Set up a fan to blow sideways. The dense particles are more likely to fall into the box, while the less-dense particles are more likely to be blown off to the side. You will probably need several iterations of this.
What is a substance that has a mass of 45 kg and a volume of 43 m3?
There is no element or common compound with a density of 45kg/m3 = 1.047 kg/m3. But it could be a mixture of two or more substances: at least one of which has a higher density and at least one has a lower density.
Heterogeneous matter composed of two or more pure substances each of which retains its identity and specific properties?
I believe you are talking about a mixture. A mixture is a physical blend of two or more substances where each substance retains its own properties. Since they keep their properties, mixtures can be separated into their original individual substances. Example: If you had a mixture of salt and sand, you could separate them by pouring the mixture into a container of water. Salt is soluble in water and will dissolve. You can then pour the salt water through a filter, capturing the sand. Then, by evaporating the water, the salt will be left.
How could you separate a mixture of small pieces of copper?
add alcohol
A mixture of fine sand and water could be separated by?
Using a centrifuge to separate by density.
If you have a mixture of substances with different - sized molecules. How could you separate them?
pour the mixture through a filter that will let the smaller substance through, but not the larger one.

If you made a mixture of iron fillings and salt how could you separate that mixture into its 2 original substances?
Place the mixture in water. You recover the iron once the salt dissolves. Then allow the water salt mixture to dry and allow salt crystals to reform.
How can you separate substances of different densities?
Density Column to Separate Mixtures of SolidsYou could use a density column to separate mixtures of different solids by adding substances that have different densities. Then you would add in the solids, which would land or stop at a substance.
What physical properties would help you distinguish between a pure substance and a mixture?

If you have a mixture made of two substances one with a higher density than the other. how could you separate the substances in the mixture?
Winnowing. Run the powder through a sifting grid, and allow it to fall into a box below. Set up a fan to blow sideways. The dense particles are more likely to fall into the box, while the less-dense particles are more likely to be blown off to the side. You will probably need several iterations of this.

How could you separate the components of homogeneous mixture to the components of heterogeneous mixture?
you can answer that by your mind. you can separate it by using a wire WIREGAUSE.
How could you separate gold from a mixture of zinc and gold?
We could add HCl to the mixture of Zinc and Gold and see which one appear to separate first.
