Hydrogen Peroxide

Question

The approximate mass of H₂O₂ present in 200mL of 100 volume H₂O₂ solution is

Easy

Solution

100 Volume strength H₂O₂ Solution means
1ml of H₂O₂ solution produces → 100ml of "O₂"
200ml of H₂O₂ solution produces → ?? of "O₂"

$\large \mathop {2{H_2}{O_2}}\limits_{2mole}\rightarrow \;\;2{H_2}O\; + \;\mathop {{O_2}}\limits_{1mole}$

2 x 34 gr of H₂O₂ solution ------------1 x 22.4lit
??gr of H₂O₂ solution ------------20lit[20,000ml]

$\large \frac{20lit\;\times\;2\;34gr}{22.4\;lit}\;60.71gr(W/V%)$
