The amount of H2O2 present in 1 litre of 1.5 N H2O2 solution, is (a) 25.5 g (b) 3.0 g (c) 8.0 g (d) 2.5 g

Correct answer: (a) 25.5 g Explanation: Molecular weight of H2O2 = 34 Equivalent weight of H2O2 = 17 ∴ 1 L of 1 N H2O2 has = 17 g of H2O ∴ 1 L of 1.5 N H2O2 has = 1.5 × 17 = 25.5 g of H2O2

Correct answer: (a) 25.5 g

Explanation:

Molecular weight of H₂O₂ = 34

Equivalent weight of H₂O₂ = 17

∴ 1 L of 1 N H₂O₂ has = 17 g of H₂O

∴ 1 L of 1.5 N H₂O₂ has = 1.5 × 17

= 25.5 g of H₂O₂
