Please help me find the molar concentration and molar mass of the acetic acid.
Data and Calculations 1. Measurement of pH and titration of acetic acid solution Concentration of standardized NaOH titrantmol/L Mass concentration of acetic acid04 25.35m㫠g/L Trial 1 Trial 2 2.94 Measured pH of the acetic acid solution Mass of acetic acid solution taken for titration I go. en g I Initial buret reading of NaOH titrant Final buret reading of NaOH titrant Net volume of NaOH Millimoles of NaOH to endpoint of titration-24 mmoll Millimoles of acetic acid in sample Molar concentration of acetic acid solution Calculated molar mass of acetic acid 044 so. g rn ml mL mmol mmol mol/L g/mol ·SB mmol 12 mmol11 mmol mol/L mol/L &/mol g/mol Calculation of the ionization constant for acetic acid from the measured pH of the acetic acid samples. (Average the pH and molar concentration values for the samples of acetic acid you titrated; use the average values in the calculation of the ionization constant)
