Density can be found by the formula ρ=m/V
where
ρ=density (kg/m3 or g/cm3)
m=mass (kg or g)
V=volume (m3 or cm3)
To find the density of iron, you must first know the mass of iron at a certain volume.
You can do this by using laboratory apparatus such as a measuring cylinder and/or a displacement can to find the volume of a piece of iron. Then using an electronic balance, find the mass of the same piece of iron.
Iron filings may be pure elemental iron, it depends on the source of the iron.

Yes, you can distinguish iron filings from sulfur by using a magnet. Iron filings are attracted to the magnet and can be separated from sulfur, which is not magnetic.
Aluminum and iron can be differentiated because iron is magnetic and aluminum is not. To separate them, expose the filings to a magnetic source and the iron will separate.
Yes, iron filings are magnetic.
Copper filings are not attracted to a magnet, as iron filings are.
The density of iron filings is about 7.87 g/cm³, table salt is 2.16 g/cm³, and pepper varies but is generally around 1 g/cm³. When added to water, the individual densities will affect how they interact: iron filings will sink, table salt will dissolve, and pepper will float. Similarly, the density of sugar is around 1.59 g/cm³, and when added to water, it will dissolve as well.
The density of iron is 7,874 kg/m3 or 7.874 g/cm3. The density of iron filing is somewhat lower depending upon how fine the filings are, but I guess more than 4000 kg/m3 or 4.0 g/cm3. The SI standard of density is measured in kg/m3. The density of a material is defined as its mass per unit volume. The density of iron does not change with the size of the sample. A bucket full of iron filings will have a lower density than the block because there will be air between the individual filings. The density of a deep pile of filings will be greater than a thin pile because the weight of the filings above compacts the filings below by pushing out some of the air. However, the density of each individual piece will still be the same as for the whole block.
The density of pure aluminum is 2.7.Filings have a packing ratio of roughly 0.6 so the density of the filings is about 1.6. this of course depends greatly on the size and shape of the filings.
One method to separate iron filings and sulfur is to use a magnet. The iron filings are attracted to the magnet and can be easily separated from the sulfur. This method takes advantage of the magnetic properties of iron filings.
Sulfur and iron filings together are a mixture.
One way to separate copper strands and iron filings is by using a magnet. Copper is not magnetic but iron is, so you can use the magnet to attract and separate the iron filings from the copper strands. Alternatively, you could also use the difference in density between copper and iron to physically separate them using techniques like flotation or panning.

Dry iron filings and wet iron filings have different physical properties. Dry iron filings are free-flowing and easily spread out, while wet iron filings clump together due to the presence of water. Additionally, wet iron filings may rust more easily due to the moisture content.
