During estimation of nitrogen 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, neutralized 10 mL of 1 M H_(2)SO_(4) . Find out the percentage of nitrogen in the compound.

Nitrogen is estimated in organic compounds by

For the estimation of nitrogen, 1.4 g of an organic compound was digested by Kjeldahl's method and the evolved ammonia was absorbed in 60 mL of M//10 sulphuric acid. The unreacted acid required 20 mL of M//10 sodium hydroxide for complete neutralisation. The percentage of nitrogen in the compound is
