The balanced chemical equation is:
2H2 + O2 ---> 2H2O
We are given the amount of the product produced from the reaction. This will be the starting point for the calculations.
355 g H2O ( 1 mol H2O/ 18.02 g H2O) ( 1 mol O2 / 2 mol H2O ) ( 32 g O2 / 1 mol O2 ) = 315.205 g O2

See explanation
Explanation:
The p orbital is threefold degenerate. This implies that the p-sublevel is composed of three orbitals; px, py and pz.
According to Hund's rule, electrons occur singly when filling degenerate orbitals before pairing takes place. Since the three orbitals are degenerate, any of px, py or pz may be first filled.
If one lobe of any of the px, py or pz is first filled, the next electron must go into the next degenerate orbital. When all are filled, pairing of electron spins may now begin.
