Hydrogen Peroxide

Question

What is the volume strength of 200 ml of aqueous H₂O₂ solution containing 6.8 gm of H₂O₂

Moderate

Solution

$\large M=\frac{Wt}{MW}\times \frac{1000}{V(in wt)}$ [M = molarity of H₂O₂ solution]
$\large M=\frac{6.8}{34}\times \frac{1000}{200}$
M = 1.0M
$\large M=\frac{vol.strength}{11.2}$
Volume strength = M x 11.2 =1x11.2 = 11.2
