a) 0.132g of a pure carboxylic acid (R-COOH) was dissolved in 25.00mL of water and titrated with 0.120M of standardised NaOH solution. A volume of 14.80mL was required to reach the endpoint of the titration.Identify the carboxylic acid.b) A 0.670g sample of barium hydroxide is dissolved and diluted to the calibration mark in a 250.0mL volumetric flask. It was found that 11.56mL of this solution was needed to neutralise 25.00mL of nitric acid solution. Calculate the molarity of the nitric acid solution. Write a chemical equation in your response.c) One student's results are given below:- Concentration of NaOH(aq) = 0.110M- Volume of undiluted vinegar = 10.00mL- total volume of diluted vinegar = 100.00mL- volume of diluted vinegar used in each titration = 20.00mL- Avg. titre of NaOH(aq) = 15.35mLBased on these results, calculate the concentration, in mol L-1, of acetic acid in the undiluted vinegar solution.
