Question

Normality is same as Molarity for sodium hydroxide and normal = molar (for NaOH)
Normality of sodium hydroxide = 0.10395N (normal) or Molarity of NaOH = 0.10395M (molar)
Volume of NaOH consumed during the titration = 21.87 mL
Mol wt of Naproxen = 230.26 g/mol
Weight of Naproxen ds (i.e., sample) = 0.534g

Calculate the % Purity (dried-basis) of Naproxen ds, given that the LOD results for Naproxen = 1.0%
