Hi guys,
I'm stuck on a question for homework. If you can show the steps I'd really appreciate it. My book is being mean and not letting me understand.
A student wishing to confirm the claims on the label of a hydrogen peroxide bottle decided to react some of its contents with a standard sln of 0.372 mol L of KMnO4. Exactly 25.00mL of "100 volume" hydrogen peroxide was added to a 250.0 mL volumetric flask and made up to the mark with water. Taking 25.00 mL aliquots from this, he titrated each one against the standardized potassium permanganate. The average volume was 26.20 mL. Calculate the volume of oxygen given off by each litre of hydrogen peroxide.
