The chemical reaction is:
2 NaOH + CoCl2 = 2 NaCl + Co(OH)2
The balanced equation for the reaction between cobalt chloride (CoCl2) and ammonia (NH3) would be: CoCl2 + 6NH3 → [Co(NH3)6]Cl2

When CoCl2·6H2O is heated, the water molecules are driven off, leaving anhydrous CoCl2. This is a physical change, not a chemical reaction. However, the anhydrous CoCl2 can undergo chemical reactions depending on the conditions and other reactants present.
The molecular equation for the reaction between cobalt II chloride and lithium carbonate is: CoCl2 + Li2CO3 -> CoCO3 + 2LiCl
The balanced equation for the reaction between cobalt(II) chloride and silver nitrate is: CoCl2 + 2AgNO3 -> Co(NO3)2 + 2AgCl.
The balanced molecular equation for FeCl3 + CoCl2 is: 2FeCl3 + 3CoCl2 → 2FeCl2 + 3CoCl3

To answer this question you need the molecular weight of CoCl2. CoCl2 molecular weight is 129.84 g/mole 230g CoCl2 divided by the molecular weight 230 g / 129.84 g/mole = 1.77 moles of CoCl2 Multiply the moles by Avagodro's number 1.77 mole * 6.022 X 1023 molecules/mole = 1.07 X 1024 molecules of CoCl2

Hypothetically speaking, this has to do with the molecular bonding of ions between the two compounds. i may be off a little bit.
CoCl2 is an ionic compound. It is made up of cobalt (Co) and chloride (Cl) ions, where the cobalt ion has a charge of +2 and the chloride ions have a charge of -1. Ionic compounds are formed by the transfer of electrons between metal and nonmetal atoms.
The gram equivalent weight of CoCl2 is calculated by dividing the molar mass of CoCl2 by its valency. The formula weight of CoCl2 is 129.84 g/mol. Since the valency of CoCl2 is 2, the gram equivalent weight would be 129.84/2 = 64.92 g/equiv.
The ionic compound CoCl2 is called cobalt(II) chloride.
