The titrations involving conductometric and potentiometric
measurements of acetylsalicylic acid (C9H804) with a standardized
solution of sodium hydroxide (NaOH) resulted in the graphs of
figure 9 whose reaction is expressed in figure 10. Calculate the %
m/m of AAS considering a mass of standard of 600 mg.
