Could you please help me figure out how to calculate the quantity in volume (Liter) of oxygen (gas) from 200 grams of hydrogen peroxide (H2O2) and 55 grams of peracetic acid (CH3COOOH)?
2H2O2(aq) -------> 2H2O + O2 (g)
2CH3COOOH(aq) -------> 2CH3COOH + O2 (g)
(Temperature =20 C, Pressure = 1 atp)
Thank you very much.

Dear convert-me.com forum visitors,
Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.
All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page
Thank you for being with us and sorry for any inconveniences this could caused.

Steps:
1) Determine the molegular weights of the relevant reactants
(rounded values H2O2 is 34, O2 is 32), and compute the number of moles of H2O2 available
2) Note from the equation that 2 moles of H2O2 produces 1 mole of O2 and determine moles of O2.
3) Use the Ideal Gas Equation, PV = nRT, to determine the volume, at the specified conditions, of that many moles of O2.
4) Follow the same general approach for the 2nd problem.
