!! Hey Mate !!
your answer is ---
Firstly , we write the equation of formation of water --
✔✔ H2 + O2 ==> 2H2O
we know that by Stoichiometric calculation , coefficient of symbol represent it's mole .
Now, we use mole to mole relation
According , to above equation
1 mole of O2 produce 2 mole of H2O
such that , 2 mole H2O = 1 mole O2
=> 1 mole H2O = 1/2 mole O2
=> 5 mole H2O = 5×1/2 = 2.5mole O2
Hence, 2.5 mole O2 is needed to make 5 mole of H2O
