Molecular mass of compound
=60g/moleThus 1 mole of compound contain =60g
in 1 mole of compound.
C is 40%=60×40100=24g
Moles of carbon in 1 mole of compound =24g12g/mole=2mole
In 1 mole of compound
H is 6.7%=60×6.7100=4.02g
Mole of H in 1 mole of compound =4.02g1g/mole≃4mole
In 1 mole of compound
O is 53.3%=60×53.3100=31.98g≃32g
Mole of O in 1 mole of compound =32g16=2mole
Thus 1 mole of comppound give
2 mole of C, 4 mole H, 2 mole of O
Thus formula of compound is C2H4O2
