H2+1/2O2=H2O.
2+32/2=18.
18H2O=08O2,
So,
90H2O=16/18*90. O2.
O2= 16*5 =80 kg O2.
2+32/2=18.
18H2O=08O2,
So,
90H2O=16/18*90. O2.
O2= 16*5 =80 kg O2.

(16/18) * 90 = 80.

H2+1/2O2---> H2O.
2+1/2 * 32=18.
Now taking
H2O:O2,
18:16,
1:16/18,
90:16/18 * 90,
= 80.
2+1/2 * 32=18.
Now taking
H2O:O2,
18:16,
1:16/18,
90:16/18 * 90,
= 80.

H2+2O2 = 2H20.
90 grams of water = 5 moles of water (moles=weight/molecular weight)
That means 2 moles of O2 = 2 moles of H2o,
?moles of O2 = 5 moles of H2O,
5x2÷2 = 5 moles.
Convert moles of O2 to the weight of O2 get 80 gms.
90 grams of water = 5 moles of water (moles=weight/molecular weight)
That means 2 moles of O2 = 2 moles of H2o,
?moles of O2 = 5 moles of H2O,
5x2÷2 = 5 moles.
Convert moles of O2 to the weight of O2 get 80 gms.

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.
