Answer:

  • 3.0M

Explanation:

The dilution formula is:

       [tex]M_1\times V_1=M_2\times V_2[/tex]

Where M₁ and M₂ are the molar concentrations and V₁ and V₂ are the volumes of the concentrated and the diluted solutions.

Substitute:

  • M₁ = 6.0M
  • M₂ = unknown
  • V₁ = 251 mL
  • V₂ = 500. mL

         [tex]6.0M\times 251ml=M_2\times 500.ml[/tex]

Clear M₂ and compute:

         [tex]M_2=6.0M\times 251ml/500.ml\approx3.0M[/tex]
