3) A student dissolves a 1.18g aspirin tablet in water and titrates the
solution with a .265M NaOH. 22.05mL of NaOH are required to reach the
equivalence point. Calculate the percentage of acetylsalicylic acid in the tablet.

  • Chemistry -

    moles NaOH needed = M x L = ??
    moles ASA = same as moles NaOH since this is a 1:1 titration. I assume you know the reaction.
    grams ASA = moles ASA x molar mass ASA.

    %ASA = (grams ASA/mass sample)*100 = ?
