' 25 volume' hydrogen peroxide means

Options

  1. A1   L marketed solution contains 250   g of H 2 O 2 .
  2. B1   L marketed solution contains 75   g of H 2 O 2 .
  3. C100   mL marketed solution contains 25   g of H 2 O 2 .
  4. D1   L marketed solution contains 25   g of H 2 O 2 .

Correct answer

B. 1   L marketed solution contains 75   g of H 2 O 2 .

Step-by-step solution

25 volumes' H 2 O 2 means: 1   L of H 2 O 2 on decomposition give 25   L of O 2 (g) at STP . 2 H 2 O 2     ( l )   →   2 H 2 O   ( l )   +   O 2   ( g )   2 [ 25 22 . 4 ] mole                                           [ 25 22 . 4 ] mole Mass of H 2 O 2 = 2   ×   25 22 . 4   ×   34   =   75   gram
