Which has a greater mass, a kilogram of feathers or a kilogram of iron? which has a greater density? explain.

So, you asked which has the greatest mass , a kilogram of feather or a kilogram of iron.

They both have the same on mass, but on the volume they both going to be  be different. The reason why is going to be different is because of the  kilogram's smaller volume than the kilogram of feathers. So the density of iron would be greater.

Hope this helped you

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).

yes the answer is total mass in unchanged   : )
