Answer by Mef
I’m not confident if I entirely recognize your question, but higher density polymer ceramics are not metals, if that is what you ended up asking about.

Answer by Denis S
Some poker chips have an insert. Some use a resin that truly has bits of metal in it to increase the density (and for this reason the fat) and give it that metal feel.

Remedy by Derrick
I concur with Meff. Metals and composites are different.

density polymer–: How do i calculate proton density ,from the provided polymer sample density?
sample density is .0081 g/cm3


The subsequent is the remedy: (Hint: The appropriate answer supplied by the users, does not assure the right.)

Solution by Dr. C
That is a hard 1. In truth, it isn’t doable unless you know the isotope concentrations for the sample. If you know the chemical composition of the polymer, you could assume a “normal” isotope distribution for every species (i.e. use the typical masses in the Periodic Table).

So, if you do know the chemical composition, you could count up the integer number of protons in each and every molecule and divide by the mass of the molecule (in g). If the polymer is comprised of many distinct molecules, you want to make a weighted sum of the ratios to get the common #p to mass ratio. If you multiply the #p to mass ratio by your density, you need to stop up with the #p per cm^three.

What do you assume? Answer below!

Identifying unfamiliar polymers by their density. Comply with the movement chart and see if each and every polymer sinks or floats in the liquid it’s positioned in to establish its relative density and arrive to an identification. If a polymer is floating, make certain it is in fact floating and not sticking to the surface by way of surface tension. Do this by forcing the pellet to submerge, then see if it floats back again up. This is employed in the Crime Busters and Forensics activities.
