1.216 gm of an organic compound was reacted under Kjeldahl's method and the ammonia evolved was absorbed in 100 ml `NH_2SO_4`. The remaining acid solution was made up to 500 ml by the addition of water. Twenty millilitres of the dilute solution required 32 ml `(N)/(10)` caustic soda solution for complete neutralisation. Calculate the percentage of nitrogen in the compound.
