The sawdust.
Density is the property that relates mass and volume (density = mass/volume). So the more dense something is, the less space a fixed mass of that material will take up.
As iron is considerably more dense than sawdust (or any solid wood for that matter) it will take up much less space.
They both weigh 1kg....... so they weigh the same,
Not sure if this is a serious question but...A kilogram is a unit of mass, or in this case, weight.A kilogram is a kilogram.One kilogram of anything is a kilogram.1 kg of iron = 1 kg of wool.
On the moon, because of the mass difference between the moon and the Earth, it would weigh 1/6th of kilogram.
1 kilogram is 1 kilogram no matter what the substance.
The answer is yes because one is twice the weight of the other and is made of exactly the same material. The answer would be "No" if the materials differed.

All you have to do is put a magnet over the mess of sawdust and iron fillings and the iron fillings will get stuck to the magnet. Then their seperated
Iron is magnetic; so, the iron filling is pulled/ is attracted to the magnet. The sawdust is not magnetic, so it will stay where it is, and will eventually be separated from the iron and the magnet.
You have to use a magnet to collect the Iron Filings
Well, iron is magnetic so you could use a magnet to remove the nails from the sawdust while leaving the sawdust, which is not magnetic, behind.
Iron has a greater density.
Use a magnet to seperate the iron. Then, add water to dissolve the salt and float the sawdust. Skim off, sieve or filter the solution to seperate the sawdust. Let the water evaporate, leaving the salt behind.

If they are iron filings, you can use the property of magnetism to remove the iron filings using a magnet. You will need to rinse the iron filings with water after you remove them with the magnet in order to completely remove the sawdust from them.
Use a magnet to separate the iron filings, filter the remaining sawdust and sugar water solution, evaporate the water from the sugar water solution.

you would use the iron's magnestism to extract it with a magnetic tube
