A 100.0 mL bottle of hydrogen peroxide contains 60.0 mL of 0.100 M H2O2(aq), leaving a volume of 40.0 mL of gas above the liquid in the 100.0 mL bottle. The gas volume initially contained air at a pressure of 1.00 atm. Determine the final pressure, at 298 K, in the sealed container when all the hydrogen peroxide in solution has decomposed.
