Question

$100{cm}^3$ of a given sample of $H_2{O}_2$ gives $1000{cm}^3$ of $O_2$ at S.T.P. The given sample is :

• A. 10% $H_2{O}_2$
• B. 90% $H_2{O}_2$
• C. 10 volume $H_2{O}_2$
• D. 100 volume $H_2{O}_2$

Answer 1

The correct option is C 10 volume $H_2{O}_2$

$2H_2{O}_2⟶2H_{2}O+O_2$
$100ml$ $1000ml$

or, $1ml$ of $H_2{O}_2$ will give $10ml$ of $O_2$ at S.T.P.

Thus, its volume strength is $10$ volume.
