    C₂ = 0.149 M

    Explanation:

    Given dа ta:

    Initial concentration = 0.407 M

    Initial volume = 2.56 L

    Final volume = 7.005 L

    Final concentration = ?

    Solution:

    Formula:

    C₁V₁ = C₂V₂

    C₁ = Initial concentration

    V₁ = Initial volume

    C₂ = Final concentration

    V₂ = Final volume

    Now we will put the values.

    0.407 M * 2.56 L = C₂ * 7.005 L

    1.042 = C₂ * 7.005 L

    C₂ = 1.042 M. L / 7.005 L

    C₂ = 0.149 M
