The formula for chromium (III) nitrate is Cr(NO3)3. The formula can be written as [Cr(NO3)3] or as Cr[NO3]3.
Chromium (III) nitrate is a colorless solid that is soluble in water and alcohols. It has a molar mass of 181.54 grams per mole, which is very close to the molar mass of chromium (III) sulfate ([Cr(SO4)2]), which has a molar mass of 182.44 g/mol.
The chemical formula for chromium nitrate can also be written as CrO4-, where the O represents an oxygen atom and the 4 represents four atoms of oxygen per molecule of chromium nitrate. This notation is used when referring to chemical formulas in older texts, but it is considered incorrect today because it does not properly represent the chemical bonds between atoms in a compound or ion.
