Explain the estimation of nitrogen of an organic compound by b) Kjeldahl's method

Differentiate between the principal of estimation of nitrogen in an organic compound by (i) Kjeldehl's method and (ii) Dumas method.

Explain the method of purifying a solid organic compound

During the estimation of nitrogen in an organic compound by Kjeldhal's method, the ammonia evolved from 0.5g of the compound was absorbed in 50 ml of 0.5 M H_(2)SO_(4) . The residual acid required 60 ml of 0.5 M NaOH solution. The percentage of nitrogen in the compound is

During the estimation of nitrogen in an organic compound by Kjeldhal's method, the ammonia evolved from 0.5g of the compound was absorbed in 50 ml of 0.5 M H_(2)SO_(4) . The residual acid required 60 ml of 0.5 M NaOH solution. The number of grams of NH_(3) releaed in the process is
