The density of osmium is slightly greater than that of iridium; the two are so similar (22.587 versus 22.562 g/cm 3 at 20 °C) that each was at one time considered to be the densest element. Only in the 1990s were measurements made accurately enough (by means of X-ray crystallography ) to be certain that osmium is the denser of the two.
— "Values ranging from 21.3 to 21.5 gm/cm 3 at 20 °C have been reported for the density of annealed platinum; the best value being about 21.45 gm/cm 3 at 20 °C." 21.46 g/cm 3 — Rose, T. Kirke. The Precious Metals, Comprising Gold, Silver and Platinum .
Note A at Iridium says "At room temperature and standard atmospheric pressure, iridium has been calculated to have a density of 22.65 g/cm3 (0.818 lb/cu in), 0.04 g/cm3 (0.0014 lb/cu in) higher than osmium measured the same way.
Mercury is the heaviest liquid at room temperature. But the heaviest liquid irrespective of temperature is liquid osmium (a rare metal) at its melting point (3033°C/5491.4°F), with a density of 22.59 g·cm −3, 1.65 times as heavy as mercury. [4]
Osmium is denser by about 0.1%. See iridium#Characteristics which discusses the issue and provides some references. --Itub 16:50, 23 September 2008 (UTC) I updated the ranking and densities of osmium and iridium as per their respective articles. Unfortunately I suspect the degree of accuracy required to split these two elements means that the ...
As for “dos” when talking to pregnant women, Kylie urged listeners to keep their opinions on baby names to themselves and to check in and see how their pregnant friend is feeling.
To simplify comparisons of density across different systems of units, it is sometimes replaced by the dimensionless quantity "relative density" or "specific gravity", i.e. the ratio of the density of the material to that of a standard material, usually water. Thus a relative density less than one relative to water means that the substance ...
Winds gusting over 100 miles per hour prevented air support from helping to douse the flames with other water sources. "We had a tremendous demand on our system in the Palisades.
