A 10.00-mL sample of vinegar (acetic acid, CH3COOH) was pipetted into a flask,
two drops of phenolphthalein indicator were added, and the acid was titrated with 0.1008 M NaOH.
(a) If 45.62 mL of the base was required for the titration, what was the molar
concentration of acetic acid in the sample?
(b) If the density of the pipetted acetic acid solution was 1.004 g/mL, what was the percentage of acetic
acid in the sample?
