Can you use density to separate insoluble liquids?
How is it used? I suppose there are many applications of density, but one that comes to mind is if you mix two insoluble liquids (like oil and water) together, the liquid with the higher or “most” density (water) will settle to the bottom of the vessel you attempted to mix the liquids in, while the liquid with the “least” density ( oil) will float to the top, so the property of density can be used to separate insoluble liquids.
What is the definition of density?
Density is how much matter is contained within a volume. A dense object weighs more than a less dense object that is the same size. An object less dense than water will float on it; one with greater density will sink. The key to solving for density is to report the proper mass and volume units.

To measure the toy's volume, fill a graduated cylinder about half way with water. Record the volume. Add the toy. Make sure to displace any air bubbles that may stick to it. Record the new volume measurement. The volume of the toy soldier is the final volume minus the initial volume. You can measure the mass of the (dry) toy and then calculate density.

Can you measure volume with a graduated cylinder?
The same goes for measuring volume. Obviously, you'll get a more precise measurement using a graduated cylinder than using a beaker, however, you may not need such a close measurement. The significant figures reported in the density calculation are those of your least precise measurement.

Another important concept to keep in mind is whether your answer makes sense. If an object seems heavy for its size, it should have a high density value.
What is weight density?
Weight density is weight of a substance per unit volume.

How does specific gravity affect density?
The relationship between specific gravity and density is the same as that between the weight and mass of a substance. The density has to do with the level of accumulation of matter in an object or substance, ie, the amount of material that comprises; and since the specific weight is nothing more than the force with which the Earth attracts a unit of mass of said matter, it is evident that a substance whose particles are denser together, that is, more compact than others, will be attracted with more force by gravity than other more dispersed particles.
