It is going to need to be divide by the original density and then after you find that out you get your answer.
If aluminum bar is cut in half What is the density of each half compared to the original density of the bar?
the density would stay the same-
Exactly the same.
Exactly the same.
+3 for Al, -1 for each Cl
The density is a specific property of all materials; the density is very important for the technology and science.
The masses of each are 8.1 cm3
We can't tell that from the density. All we know is that however much aluminum foil you have ... whether it's a tiny scrap or a truckload ... each cm3 of it has 2.7g of mass.
The density of steel is greater than that of aluminium, A centimetre cube of each, if placed on a weighing balance would show that the steel has greater density because its side of the balance arm would sink.
The density of the foils is the same. They are both pure aluminum, and they each have the same weight per unit volume (density). But the thicker "heavy duty" foil will weigh more for a given area of foil removed from a roll. This makes sense because the heavy duty foil is thicher, and something like, say, as square foot of this heavy duty foil will outweigh a square foot of "regular" foil.
The density of solid aluminum is 2.7 gm/cm3. It has absolutely nothing to do with the size of the sample. It can be a 2 cm cube or a block the size of the starship Enterprise. Makes no difference. Still 2.7 .
Molecular Weight: 26.98The density of industrial qualities of aluminum lies around 2.7A cube 10cm each edge weighs 2700 grams
Exactly the same.
Exactly the same.
You are asking for comparatives. Each state can be any when compared to another state except the extremes. Liquid or gas either lower or higher depending on what you compare it to.
Each metal has a unique, characteristic density. Aluminum metal is of much lower density than iron, for example--something that you can readily observe if you have equal-volume solid blocks of each metal. The iron will be obviously more massive. Density of any metal varies a small amount with temperature--increasing as temperature increases, so for complete accuracy assume the above applies to solid samples of metal at the same temperature.

how much aluminum is made new from ore each year
Take each nail and weigh it. Then use water displacement to find its volume. Use these two pieces of data to find the density. If the nail's density is about 2.70 g/cm3, then it's aluminum. If it is about 7.87 g/cm3, then it is an iron nail. Do this for every nail.
