Full Answer

If the compound were to contain a chromium (III) ion instead of a chromium (II) ion, its chemical formula would be CR(NO3)3; the additional nitrate ion would be needed to balance out the positive electrical charge of chromium (III). Chromium nitrate can be produced by combining chromium oxide in nitric acid solution. The molar mass of chromium (II) nitrate is 176.0059 grams per mole. Chromium (II) nitrate finds limited uses in the dyeing industry.
