Chapter 6, Problem 52E

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.
${\text{2 H}}_{\text{2}}{\text{O}}_{\text{2}}\left(\text{aq}\right)\to {\text{2H}}_{\text{2}}\text{O}\left(\text{I}\right){\text{+O}}_{\text{2}}\left(\text{g}\right)$
