(Answered) You have 2500 ml of 3 by mass solution of hydrogen peroxide

Academics

You have 25.00 mL of 3% by mass solution of hydrogen peroxide. Assume the density of this solution is 1.00 g/mL. If all of the hydrogen peroxide decomposes to water and oxygen according to the reaction below:

2H₂O₂ (aq) <--> 2H₂O (l) + O₂ (g)

What is the total volume of oxygen gas generated if the temperature is 24 degrees C and the pressure is 770 Torr. (R = 0.08206 L atm/K mol) At this point you may ignore the effect of water vapor.
