    Final volume in milliliters, V₂ = 1515 mL

    Explanation:

    Initial concentration of the solution, C₁ = 32.9 % (m/V)

    The initial volume in Litres, V₁ = 0.967 L

    Final concentration on dilution, C₂ = 21.0 % (m/V)

    The Final volume in Litres, V₂ = ?

    Using the dilution formula:

    C₁V₁ = C₂V₂

    0.967 * 32.9 = 21 * V₂

    31.8143 = 21 * V₂

    V₂ = 31.8143/21

    V₂ = 1.515 L

    V₂ = 1.515 * 1000

    V₂ = 1515 mL
