The density is a property that measures how efficiently a substance is spatially packed. The relationship between the mass, volume, and density of a substance is:

 This drastic change in density between the various forms of carbon is a consequence of the crystalline structure that each substance adopted. The macroscopically measured density is usually slightly different than that measured using X-ray diffraction because of defects and/or impurities within the sample.
