Calculate the number of moles of hydrogen peroxide reacted. (remember the hydrogen peroxide solution is a 3% solution. you weighed 3.5 g of a h2o2 solution, of which only 3% was h2o2.) 2. using equation (1), calculate the number of moles of oxygen that should have been produced by the decomposition of the number of moles of h2o2 calculated in 1. 3. from the volume of oxygen measured, the temperature, and the pressure, use the ideal gas law to calculate the number of moles of o2 produced by the decomposition of h2o2. be sure to correct the pressure for the contribution from the vapor pressure of water. compare the number of moles of o2 calculated here using the ideal gas law with the number of moles of o2 calculated in question 2 above. do your results verify the ideal gas law? 4. use the ideal gas law as in question 3 to calculate the number of moles of oxygen produced by the solution with unknown wt% h2o2. 5. from the answer to question 4, calculate the number of grams of h2o2 in the sample and the concentration in weight % of the unknown solution. assume the density of h2o2 is 1.00 g/ml.
