Answer : The molarity of
in the solution is 1.5 M.
Explanation : Given,
Moles of
= 3.0 mol
Volume of solution = 2.00 L
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :

Now put all the given values in this formula, we get:

Therefore, the molarity of
in the solution is 1.5 M.
they all have one thing in common and that its all made up of atoms. When these components are active it creates energy
2Al+3Cl2==>2AlCl3
(4mol Al)(2 mol AlCl3/2 mol Al)=4 mole AlCl3
