0.45 gm of an organic compound gave on combution 0.792 gm of `CO_2` and `0.324gm` of water. 0.24 gm of the same substance was Kjeldahlised and the ammonia liberated was absorbed in 50.0 ml of `(M)/(8H_2SO_4)`. The excess acid required 77.0 ml of `(N)/(10)NaOH` for complete neutralisation. Calculate the empirical formula of the compound.
