2H2 + O2 = 2H2O.
So, we can say that 1 mole of O2 gives 2 moles of H2O.
Now from the formula,
Mass = M.W. × Moles
We can get 90 kg [90000 gm] of H2O containing 5000 no. of moles.
Now, 2 moles H2O = 1 mole O2.
5000 moles H2O= ?
So, we get 2500 moles of O2.
Now by converting moles into mass we get 80000 gm or 80 kg of O2.
So, we can say that 1 mole of O2 gives 2 moles of H2O.
Now from the formula,
Mass = M.W. × Moles
We can get 90 kg [90000 gm] of H2O containing 5000 no. of moles.
Now, 2 moles H2O = 1 mole O2.
5000 moles H2O= ?
So, we get 2500 moles of O2.
Now by converting moles into mass we get 80000 gm or 80 kg of O2.
