A sample of 0.50
Given that, total mass of organic compound=0.50g
60ml of 0.5M solution of NaOH was required by residual acid for neutralisation.
60ml of 0.5M NaOH solution =ml of 0.5M H2SO4
=30ml of 0.5M H2SO4
Therefore, acid consumed in absorption of evolved ammonia is (50-30)ml=20ml
Again,20ml of 0.5M H2SO4=40ml of 0.5M NH3
Therefore, 40ml of 0.5M NH3 will contain=
=0.28g of N
Therefore, the % of nitrogen in 0.50g of organic compound==56%.
