1. Calculate the number of moles of O2 produced using the ideal gas law. Then, use this value to calculate the number of moles of hydrogen peroxide you began the experiment with. HINT: Use the balanced equation provided in the lab introduction. 2. Calculate the number of moles of hydrogen peroxide you would have if you used 5 mL of a pure hydrogen peroxide solution. HINT: The density of hydrogen peroxide is 1.02 g/mL. 3. Determine the percentage of hydrogen peroxide in your solution. 1.02 g/mL * 5 mL = 5.1g / 34 g = 0.15 mol 4. Was the calculated percentage of hydrogen peroxide close to the same as the percentage on the label (3%)? Calculate percent error of your value.
