Question

quantity of oxygen required for complete combustion of one mole of an organic compound c x h y Oz​

Answer 1

Answer:

The empirical formula of an organic compound containing carbon and hydrogen is CH2. The empirical formula mass is 14 g/mol respectively.

The mass of one litre of this organic gas is exactly equal to that of one litre of N2. In other words, the mass of one mole of this organic gas is exactly equal to that of one mole of N2 (as volume is directly proprotional to the number of moles). It is equal to 28 g/mol.

n=empirical massMolecular mass=1428=2

Therefore, the molecular formula of the organic gas is 2×CH2=C2H4.
