The catalytic decomposition of hydrogen peroxide yields oxygen gas and water, according to the reaction given below. in an experiment, the decomposition of hydrogen peroxide yielded 75.3 ml of gas collected over water at 25°c and 0.976 atm. (water = 0.032 atm at 25°c) 2 h2o2(aq) → 2 h2o(l) + o2(g) if the original h2o2 solution had a volume on 500 ml, what was the molar concentration of hydrogen peroxide prior to decomposition?
