The energy needed to break the bonds of 2 moles of O2 gas would be 968 jk/mol.
What is a chemical bond?
A bond is a term that refers to the attractive interaction between atoms and molecules.
The energy needed by moles to interact is measured in joules per mole and is represented as follows:
In the case of O2 moles, they require 494 jk/mol, therefore, if we need to separate 2 moles of O2, we need 968 jk/mol.
