100 ~cm ^3 of a given sample of H ₂ O ₂ gives 1000 ~cm ^3 of O ₂ at S.T.P. The given sample is

Options

  1. A10 % H ₂ O ₂
  2. B90 % H ₂ O ₂
  3. C10 volume H ₂ O ₂
  4. D100 volume H ₂ O ₂

Correct answer

C. 10 volume H ₂ O ₂

Step-by-step solution

gathered 2 H ₂ O ₂ 2 H ₂ O + O ₂ 100 ~mL 1000 ~mL gathered or 1 ~mL of H ₂ O ₂ will give 10 ~mL of O ₂ at STP Thus its volume strength is 10 volume.
