Molar mass: 266.22 g·mol −1 ... Osmium(IV) fluoride is an inorganic chemical compound of osmium metal and fluorine with the chemical formula OsF 4. [1] [2]
Osmium fluoride may refer to: Osmium(IV) fluoride (osmium tetrafluoride), OsF 4; Osmium(V) fluoride (osmium pentafluoride), OsF 5; Osmium(VI) fluoride (osmium ...
Osmium octafluoride is an inorganic chemical compound of osmium metal and fluorine with the chemical formula Os F 8. [3] [4] Some sources consider it to be a still hypothetical compound. [5] An early report of the synthesis of OsF 8 was much later shown to be a mistaken identification of OsF 6. [6]
Osmium (from Ancient Greek ὀσμή (osmḗ) 'smell') is a chemical element; it has symbol Os and atomic number 76. It is a hard, brittle, bluish-white transition metal in the platinum group that is found as a trace element in alloys, mostly in platinum ores. Osmium is the densest naturally occurring element.
Osmium(II) iodide is a black solid [35] produced by the reaction of osmium tetroxide and hydroiodic acid at 250 °C in nitrogen: [34] OsO 4 + HI → OsI 2 + H 2 O. This compound decomposes in contact with water. [35] Osmium(III) iodide is a black solid that is produced by heating hexaiodoosmic acid (H 2 OsI 6). [34] This compound is insoluble ...
The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, M u ≈ 1.000 000 × 10 −3 kg/mol ≈ 1 g/mol. For normal samples from Earth with typical isotope composition, the atomic weight can be approximated by the standard atomic weight [ 2 ] or the conventional atomic weight.
