how do you measure & compare densities of different elements

First you measure the mass of the sample in grams. The size of the sample is not important since density is an intrinsic property of matter. Just take a random sample and keep it separated from the rest of the material.
Second you measure the volume of the same sample. This can be measured in either mL or cm^3. If the chemical is a liquid use a graduated cylinder to measure the volume in mL. If the sample is a solid measure the volume of the sample in cm^3.
Density is a derived measurement using the two direct measurements mentioned above.
Density = Mass / Volume
The units of density are g/mL or g/cm^3 depending if it is a solid or liquid.

D= M/v
M= mass
v= volume
