If 60.0 ml of a 1.5 m hcl solution is put into a flask and diluted with water to make 2.0 l of solution

The molarity of the diluted HCl solution: M₂ = 0.045 M  

Explanation:

To find- the molarity of the diluted HCl solution (M₂)

Given- For original HCl solution-

Molarity: M₁ = 1.5 M, Volume: V₁ = 60.0 ml = 0.06 L          (∵ 1L = 1000 mL)

Then this original solution is diluted to a volume of 2 L

Thus for the diluted HCl solution-  

The Volume of the diluted HCl solution: V₂ = 2 L

So the Molarity of the diluted HCl solution (M₂) can be calculated by the dilution equation:

Therefore, the molarity of the diluted HCl solution: M₂ = 0.045 M

increased stability in the completion of fluorine's outer shell.
