A 25.00 ml of vinegar sample was diluted to 250 ml using a volumetric flask. A 50.0 ml aliquot portion of the dilute vinegar solution needed 35.45 ml of 0.1200 M NaOH to reach the phenolpthalein end point. (a) Calculate the no. of millimoles of NaOH required to reach the endpoint (b) Calculate the no. of millimoles of acetic acid present in the 50 ml aliquot portion that was titrated (c) Concentration of acetic acid in the titrated aliquot portion (d) The concentration of acetic acid in the volumetric flask (e) Calculate the total mass of acetic acid dissolved in the solution contained in the volumetric flask (f) The mass(g) of acetic acid dissolved in the solution contained in the volumetric flask came drom the 25.00 ml vinegar sample. Calculate the mass of acetic acid present in the 25 ml vinegar sample. (g) Calculate the % CH3COOH (w/v) present in the 25.00ml vinegar sample
