What is the Molarity of the Chloride ion (Cl-) in a 5M AlCl3 solution?

The Molarity of the Chloride ion in a 5M   solution is 15 M

Explanation:

Molarity is defined as the number of moles of solute dissolved per liter of the solution.

where,

n= moles of solute

= volume of solution in ml

Now as 1 mole of gives 3 moles of

5 moles of gives = moles of

Thus Molarity of the Chloride ion in a 5M solution is 15 M
