In which of the following compounds is the Kjeldahl method applicable?

In Dumas method for estimation of nitrogen,$0.50 \ g$ of an organic compound gave $70 \ mL$ of nitrogen collected at $300 \ K$ and $715 \ mm$ pressure. The percentage of nitrogen in the organic compound is . . . . . . $ \% $ (Aqueous tension at $300 \ K$ is $15 \ mm$).

Discuss the principle of estimation of halogens,sulphur,and phosphorus present in an organic compound.

In Kjeldahl’s method,the nitrogen present in the organic compound is quantitatively converted into

In the Dumas method for the estimation of nitrogen,$0.388 \ g$ of an organic compound yielded $1.31 \ mL$ of $N_2$ gas collected at $293 \ K$ temperature and $746 \ mm$ pressure. Calculate the percentage of nitrogen in the compound. (Aqueous tension at $293 \ K = 6 \ mm$). (in $\%$)

When $0.15 \ g$ of an organic compound was analyzed using the Carius method for the estimation of bromine,$0.2397 \ g$ of $AgBr$ was obtained. The percentage of bromine in the organic compound is $.....$ (Nearest integer).
