The amount of H ₂ O ₂ present in 1 litre of 1.5 ~N H ₂ O ₂ solution, is:

Options

  1. A25.5 ~g
  2. B3.0 ~g
  3. C8.0 ~g
  4. D2.5 ~g

Correct answer

A. 25.5 ~g

Step-by-step solution

Molecular weight of H ₂ O ₂=34 Equivalent weight of H ₂ O ₂=17 1 ~L of 1 ~N H ₂ O ₂ has =17 ~g of H ₂ O 1 Lof 1.5 NH ₂ O ₂ has =1.5 17=25.5 ~g of H ₂ O ₂
