So you have 2 moles of Chromium (Cr). Use equation moles=mass (in grams)/RMM.
The bottom can be called Relative Molecular Mass (RMM), or Relative Atomic Mass (RAM) depending on the situation. Chances are you know it as Molar mass. You can call it that too.
Using moles= mass (g)/RMM --> 2 moles = mass (g)/51.996 --> 2 x 51.996 = the mass in grams of Chromium --> 103.992g in 2 moles of Chromium.
When chromium(II) iodide is put into water, it undergoes a redox reaction where chromium(II) ions are oxidized to chromium(III) and iodide ions are reduced to iodine. This results in the formation of chromium(III) hydroxide and iodine.
The balanced chemical equation for the reaction between chromium(II) nitrate (Cr(NO3)2) and sodium hydroxide (NaOH) is: Cr(NO3)2 + 2NaOH -> Cr(OH)2 + 2NaNO3.
Cr^+2 is the symbol for the Chromium(II) ion
The formula of Chromium (II) oxide is CrO.

Chromium (ii) sulfide
Chromium II fluoride
Chromium(III) oxide has a beautiful green color.
It is called chromium(II) oxide.See the Web Links for more information.
Chromium Bromide
chromium oxide
The formula CrI2 represents chromium (II) iodide, which is a chemical compound composed of chromium and iodine ions in a 1:2 ratio.
