WebAug 1, 2024 · 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. It looks like it's close to 6% (ignoring the density of the 6% solution).
