Crystals of silver nitrate under a microscope. Silver nitrate is an inorganic compound with chemical formula AgNO 3.It is a versatile precursor to many other silver compounds, such as those used in photography.
Silver sulfate precipitates as a solid when an aqueous solution of silver nitrate is treated with sulfuric acid: . 2 AgNO 3 + H 2 SO 4 → Ag 2 SO 4 + 2 HNO 3. It is purified by recrystallization from concentrated sulfuric acid, a step that expels traces of nitrate. [7]

The concentration of pure osmium tetroxide (molar mass = 254.23 g/mol) is c (OsO 4 ) = 5.1 kg/L / 254.23 g/mol = 20.1 mol/L. A typical protein in bacteria , such as E. coli , may have about 60 copies, and the volume of a bacterium is about 10 −15 L.
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.
Silver nitride is an explosive chemical compound with symbol Ag 3 N. It is a black, metallic-looking [3] solid which is formed when silver oxide or silver nitrate [4] is dissolved in concentrated solutions of ammonia, causing formation of the diammine silver complex which subsequently breaks down to Ag 3 N.
