Tests showed that the mass was made up of abnormal, primitive cells and that it was growing very aggressively.
The international prototype standard kilogram of mass is made from an alloy containing 90 percent platinum and 10 percent iridium.
The gram, the basic unit of mass, was made equal to the mass of a cubic centimetre of pure water at the temperature of its maximum density (4 °C or 39.2 °F).
Holding less raw hydrogen and helium, perhaps 10% and mainly in their outer layers, most of their mass is made up of ices of water, ammonia and methane which may overlay an Earth-sized core of iron, nickel and silicates.
The luminosity function for M3 shows that 90 percent of the visible light comes from stars at least twice as bright as the Sun, but more than 90 percent of the cluster mass is made up of fainter stars.

The source of the keratin of the stratum corneum has been a subject of controversy; but it is now generally accepted that about a third of its total mass is made up of proteins synthesized in the granular layer and the remainder from so-called intermediate filaments, which are present in keratinocytes from the basal layer outward.
Based on these findings and the fact that body mass is the easiest patient-dependent parameter to use, the choice for body mass was made.
The dust, which accounts for a small fraction of the disk's mass, is made up of microscopic specks of iron and other solids.
