Question Solved1 Answer Hydrogen peroxide, H2O2, is used to disinfect contact lenses. How many milliliters of O2(g) at 22 °C and 1.00 bar can be liberated from 10.0 mL of an aqueous solution containing 3.00% H2O2 by mass? The density of the aqueous solution of H2O2 is 1.01 g/mL. 2 H2O2(aq) → 2H2O(1) + O2(g)
