0.36 g of a nitrogeneous organic compound was Kejldahilised and the ammonia liberated was exactly neutralised by 20 ml of 0.3 N `H_(2)SO_(4_`. Calculate the percentage of nitrogen in the compound.

During nitrogen estimation present in an organic compound by Kjeldahl.s method, the ammonia evolved from 0.5 g of the compound in Kjeldahl.s estimation of nitrogen neutralised 10 ml of 1 M H_(2)SO_(4) . Find the percentage of nitrogen in the compound.

In the estimation of nitrogen present in an organic compound by Dumas method 0.35 g yielded 20.7 mL of nitrogen at 15^(@)C and 760 mm Hg pressure. Calculate the percentage of nitrogen in the compound.

0.257 g of an organic substance was Kjeldahlised and ammonia evolved was absorbed in 50 mL of N/10 HCl which required 23.2 ml of N/10 NaOH for neutralization. Determine the percentage of nitrogen in the compound.

0.35 g of an organic substance was Kjeldahlised and the ammonia obtained was passed into 100 ml of N/5 H_(2)SO_(4) . The excess acid required 154 ml of N/10 NaOH for neutralisation. Calculate the percentage of nitrogen in the compound.

The ammonia evolved from 0.21 g of an organic compound by Kjeldahl method neutralised 15 ml of N/20 sulphuric acid solution. Calculate the percentage of nitrogen.
