5. An accurately measured 2g sample of hydrogen peroxide (H₂O₂-34g/mol) was dissolved in a mixture of 20mL water and 20mL diluted sulfuric acid. Sample is titrated with 0.1N potassium permanganate consuming 30mL to reach the endpoint. Compute for the percentage of hydrogen peroxide. 2KMnO4 + 5H₂O₂ + 3H₂SO4Ⓡ 2MnSO4 + K₂SO4 +50₂ + 8H₂O
