This preview shows page 2 - 4 out of 5 pages.

3. Convert the volume of oxygen from mL to liters (L). 4. Rearrange the ideal gas law to solve for n.
5. You are now ready to solve for the number of moles of O 2 . Be sure the units cancel so that you end up with only the moles of O 2 left. Use the value for the constant R given:
Actual moles O2 Theoretical moles O2
Now you have all of the information needed to solve the equation for the theoretical moles of O 2 . All you need to do is fill in the blanks and do the calculations. = mol
6. Calculate the theoretical number of moles of O 2 there would be if the hydrogen peroxide were 100%, and not an aqueous solution. To use the above equation, calculate the following: 2 O 2
