Question

Strength of $10$ volume hydrogen peroxide solution means

• A. $30.35g{L}^{-1}$
• B. $17g{L}^{-1}$
• C. $34g{L}^{-1}$
• D. $68g{L}^{-1}$

Answer 1

Answer: (A)

$\underset{\text{68 g}}{2H_2{O}_2}\to 2H_{2}O+\underset{\text{22.4 L at STP}}{O_2}$
$22.4L{O}_2$ is given by $68g$ of $H_2{O}_2$
$10L{O}_2$ is given by $\frac{68}{22.4}\times 10$
$=30.35g{L}^{-1}$
