A 500mL sample of O2 gas at 24 degrees Celsius was prepared by decomposing a 3% aqueous solution of hydrogen peroxide, H2O2, in the presence of a small amount of manganese catalyst by the reaction: 2H2O2(aq) -------> 2H2O(g) + O2(g) The oxygen thus prepared was collected by displacement of water. The total pressure of gas collected was 755 mm Hg. What is the partial pressure of O2 in the mixture? How many moles of O2 are in the mixture? Please note that the vapor pressure of water at 24 degrees Celsius is 23 mm Hg.
