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%
