Question

The volume strength of $1$ molar solution of $H_2{O}_2$ is:

• A. $11.2$
• B. $22.4$
• C. $5.6$
• D. $56$

Answer 1

The correct option is A $11.2$

$1$ molar $H_2{O}_2$ solution means $1$ mole (or $34g$) of ($H_2{O}_2$) present in ${10}^{3}mL$ solution.

$\therefore$ $68g$ $H_2{O}_2$ gives $=22400mL$ of $O_2$

$\therefore$ $68g$ $H_2{O}_2$ gives $=\frac{22400mL\times 34}{68}=11200mL$ of $O_2$

Volume strength $=\frac{11200}{{10}^3}=11.2V$
