Answer : The number of moles of [tex]Cl^-[/tex] ions are, 5.00 mole.
Explanation :
When 1 mole of [tex]ZnCl_2[/tex] dissociates then it gives 1 mole of [tex]Zn^{2+}[/tex] ion and 2 moles of [tex]Cl^-[/tex] ions.
As we are given that there are 2.50 mole of [tex]ZnCl_2[/tex].
Now we have to determine the number of moles of [tex]Cl^-[/tex] ions.
As, 1 mole of [tex]ZnCl_2[/tex] dissociate to give 2 moles of [tex]Cl^-[/tex] ions.
So, 2.50 mole of [tex]ZnCl_2[/tex] dissociate to give [tex]2\times 2.50=5.00[/tex] moles of [tex]Cl^-[/tex] ions.
Therefore, the number of moles of [tex]Cl^-[/tex] ions are, 5.00 mole.
There are 5.00 moles of Cl- in 2.50 moles of ZnCl2.
We have that the amount of moles of ZnCl2 is equal to 2.50 moles, so, according to the equation that forms this compound we can say that:
[tex]Zn + 2Cl[/tex] ⇒[tex]ZnCl_{2}[/tex]
So, 1 mole ZnCl2 of decomposes as 1 Zn ion and 2 Cl ions, that is, the number of moles of chlotide is twice the number of moles of ZnCl2:
[tex]2 \times 2.50 = 5.00 moles[/tex]
So, there are 5.00 moles of Cl- in 2.50 moles of ZnCl2.
