Calculate the mass of khc8h4o4 that reacts with 15 ml of the naoh solution

The balanced chemical reaction would be:

 KHC8H4O4 (aq) + NaOH (aq) → NaKC8H4O4 (aq) + H2O.

The concentration of the NaOH is equal 0.1 M. We use this and the volume given above to determine the mass of KHC8H4O4. We do as follows:

0.1 mol / L NaOH (.015 L) ( 1 mol KHC8H4O4 / 1 mol NaOH) (204 g / 1 mol) = 0.306 g KHC8H4O4
