ZnCl2 is used in soldering flux, an alloy used to join two metals together. Determine the moles of Cl- ions in 2.50 mol ZnCl2.

5.00 mol Cl-

0.500 mol Cl-

1.75 mol Cl-

15.0 mol Cl-

Answer : The number of moles of ions are, 5.00 mole.

Explanation :

When 1 mole of dissociates then it gives 1 mole of ion and 2 moles of ions.

As we are given that there are 2.50 mole of .

Now we have to determine the number of moles of ions.

As, 1 mole of dissociate to give 2 moles of ions.

So, 2.50 mole of dissociate to give moles of ions.

Therefore, the number of moles of ions are, 5.00 mole.
