`        Question Number 26 from chapter hydrogen. How is the strength calculated in terms of %?`

```							When a 3% solution of H2O2 decomposes completely, it produces 10 times as much volume of gas as was the initial volume of liquid. This is the common hydrogen peroxide available in stores. I buy it often.So, it would seem intuitive that "20 volume Hydrogen Peroxide" would be a 6% solution.To check, let's take 1 liter of H2O2 and let it decompose: 20 liters of O2 is 20/22.4 = 0.893 moles of O2. To get 0.893 moles of O2, you must have started with 2 x 0.893 = 1.786 moles of H2O2, which weighs 60.7 grams. Looks like it's close to 6% (ignoring density of the 6% solution).
