2. given the following experimental data, calculate the molarity and the pka of the acid analyte (ha) in the titration, if the balance neutralization reaction is ha + naoh à naa + h2o. a ph reading of 3.65 was obtained when 13.0 ml of 0.413 m naoh was added to the 25.0 ml analyte. the endpoint was achieved when 31.25 ml of naoh had been added.

Answer//the law of conservation of mass.;
