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.
