H2+O2=H2O
2H2+O2=2H2O
ONE MOLE OF O2 REACTS WITH TWO MOLES OF H2
TWO MOLES OF H2 WHEN REACT WITH ONE MOLE OF O2 PRODUCES 2 MOLES OF H2O
SO NOW DIVIDE 36 BY 18(MOLECULAR MASS OF H2O)
MOLES = WT./MOLECULAR MASS
=36/18
=2
SO 2 MOLES OF H2O IS FORM
2 MOLES OF H2 IS NEEDED TO PRODUCE 2 MOLES OF H2O
SO THERE IS 2 MOLES OF H2
NOW
MOLES =WT/MOLECULAR MASS
2=WT/2
SO , WT of H2 IS 4gm
2H2+O2=2H2O
