    Answer:

    V_{base}=6.0mL

    Explanation:

    Hello there!

    In this case, by considering that the reaction between sodium hydroxide and hydrochloric acid is in a 1:1 mole ratio of these two reactants, we are able to use the following equation relating the concentration and volume of each one:

    M_{acid}V_{acid}=M_{base}V_{base}

    In such a way, by solving for the volume of the base, we will obtain:

    V_{base}=\frac{M_{acid}V_{acid}}{M_{base}} \\\\V_{base}=\frac{0.5M*24mL}{2.0M}\\\\V_{base}=6.0mL

    Regards!
