QJEEM23Ch2f47: JEE Main 2023 Chemistry - Class 11 JEEM23Ch2f47 Solution: '25 volume' hydrogen peroxide means

'25 volume' hydrogen peroxide means

Multiple Choice Options

  • A 1 L marketed solution contains 75 g of H2O2.
  • B 1 L marketed solution contains 250 g of H2O2.
  • C 1 L marketed solution contains 25 g of H2O2.
  • D 100 mL marketed solution contains 25 g of H2O2.

Step-by-Step Verified Solution

Molarity of H2O2\mathrm{H}_{2} \mathrm{O}_{2} soln = volume strength 11.2=\frac{\text { volume strength }}{11.2}

=2511.2=2.23M=\frac{25}{11.2}=2.23 \mathrm{M}

∴\therefore amount of H2O2\mathrm{H}_{2} \mathrm{O}_{2} in one litre =2.23×34=75gm=2.23 \times 34=75 \mathrm{gm}
