    18.75 mL of NaCl solution is required.

    Explanation:

    Given dа ta:

    Molarity of solution one = 2.0 M

    Volume of solution one = ?

    Molarity of second solution = 0.15 M

    Volume of second solution = 250 mL

    Solution:

    M₁V₁ = M₂V₂

    V₁ = M₂V₂/M₁

    V₁ = 0.15 M * 250 mL / 2.0 M

    V₁ = 37.5 M. mL / 2.0 M

    V₁ = 18.75 mL
