Answer:

  • <u>350 mL</u>

Explanation:

Normally, in the neutralization reactions, that is how the reactions between and acid and a base are called, you assume additive volumes.

Additive volumes means that the <em>volume</em> of the final <em>solution</em> is equal to the sum of the separate volumes of the two solutions that are mixed.

It is not totally accurate, but it is a good approximation and for lack of additional data it is what is used.

Then, assuming additive volumes:

  • Total volume of the solution = 100 mL + 250 mL = 350 mL.
