    The concentration resulting solution = 0.350 M

    Explanation:

    In case of dilution, the following formula can be used -

    M₁V₁ = M₂V₂

    where,

    M₁ = initial concentration,

    V₁ = initial volume,

    M₂ = final concentration, i. e., concentration after dilution,

    V₂ = final volume.

    from, the question,

    M₁ = 0.85 M

    V₁ = 4.12 L

    M₂ = ?

    V₂ = 10.0 L

    Using the above formula, the molarity of the final solution after dilution, can be calculated as,

    M₁V₁ = M₂V₂

    0.85 M * 4.12 L = M₂ * 10.0 L

    M₂ = 0.85 M * 4.12 L / 10.0 L

    M₂ = 0.350 M
