According to the experiment
procedure, given that the NaOH
solution has a concentration of
0.100M, and that the vinegar
(acetic acid) has a concentration of
5.0%m/m (mass percent), what
volume(mL) of titrant would be
required to reach the "equivalence
point", if you place 2.500g of
vinegar in the flask (show
calculations) ?

I know this question was posted before but I don't understand how you go about a question like this can you explain?
