    Molarity of HCl = 1.3 M

    Explanation:

    Given dа ta:

    Volume of HCl = 25.0 mL

    Molarity of HCl = ?

    Volume of NaOH = 15 mL

    Molarity of NaOH = 2.0 M

    Solution:

    Formula:

    M₁V₁ = M₂V₂

    M₁ = Molarity of HCl

    V₁ = Volume of HCl

    M₂ = Molarity of NaOH

    V₂ = Volume of NaOH

    Now we will put the values.

    M₁ * 25 mL = 2.0 M * 15 mL

    M₁ * 25 mL = 30 M. mL

    M₁ = 30 M. mL / 25 mL

    M₁ = 1.3 M
