Question

A commercial sample of hydrogen peroxide is labelled as 10 volume its strength in gram per litre is


​

Answer 1

Explanation:

We know that,

Volume Strength= (68/22.4)×V [2H2O2]= O2+2H2O

So,

34×2 grams of H2O2 gives 22.4 litres O2

it implies that V volume of O2 reacts with (68/22.4)×V H2O2]

Place the values, ..

Then,

V=10 and convert it into %.

Therefore we will get 3%.

Answer 2

$percent \: concentration = \frac{68}{224} \times valume \: strength \\ \: percent \: concentration = \frac{68}{224} \times10 = 3\%$
