It forms 3 ions.
1 mole CaCl2 = 6.022 x 1023 formula units CaCl2 1.26 x 1024 formula units CaCl2 x 1mol CaCl2/6.022 x 1023 formula units CaCl2 = 2.09 moles CaCl2
For sodium oxide, the empirical formula is the same as the formula unit, Na2O. (If any formula unit or molecular formula contains an atomic symbol with no following subscript, the empirical and actual formulas will be the same.)
CaCl2 is the chemical formula of calcium dichloride.

CCl4 is molecular formula.
The 2 in CaCl2 means that there are two Cl (Chlorine) atoms in each formula unit.
A formula unit.
It forms 3 ions.
The formula unit for calcium chloride is CaCl2. There are two chloride ions in one formula unit of calcium chloride. We can also say that there are two moles chloride ions in one mole of CaCl2.
These are the ions and their charges: Ca+2 Cl-1The charges have to add up to zero, so one +2 calcium ion cancels out two -1 chlorine ions: Ca+2 Cl-1 Cl-1Simplify: CaCl2
