chem question please help
Ok, so there's .9734 g sample which contained monoprotic benzoic acid C6H5COOH and it's dissolved in 75 mL of water and titrated to the equivalence point with 31.78 mL of .09251 M NaOH solution. a) how many moles of benzoic acid were titrated b) Was this a pure sample of benzoic acid? c) If the sample is no, Calculate its percent purity.
The attempt at a solution
ok so for the first problem part a is pretty easy but then I have no idea how to determine if this sample is pure and how to calculate percent of purity.
