How much oxygen i will get from 2.5 cm3 hydrogen peroxide decompositio

1.	How much oxygen i will get from 2.5 cm3 hydrogen peroxide decomposition??
Answer» Decomposition of Hydrogen PEROXIDE: 2H₂O₂ -------> 2H₂O + O₂ 2 moles of hydrogen peroxide PRODUCES 1 MOLE of OXYGEN. So, at STP, 44800 cm³ of hydrogen peroxide produces 22400 cm³ of oxygen. Then , 2.5 cm³ of hydrogen peroxide produces (2.5 × 22400)/44800 = 1.25 cm³ of oxygen So, you will get 1.25 cm³of oxygen from 2.5 cm³ of hydrogen peroxide.
