Quantitative measurement of nitrogen in an organic compound is done by the method:

In Carius method of estimation of halogens,$250 \ mg$ of an organic compound gave $141 \ mg$ of $AgBr$. The percentage of bromine in the compound is:

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

In Kjeldahl's method for estimation of nitrogen,$CuSO_4$ acts as :

In Duma's method of estimation of nitrogen,$0.1840 \, g$ of an organic compound gave $30 \, mL$ of nitrogen collected at $287 \, K$ and $758 \, mm$ of $Hg$ pressure. The percentage composition of nitrogen in the compound is $......$ . (Round off to the Nearest Integer). [Given : Aqueous tension at $287 \, K = 14 \, mm$ of $Hg$ ]

In the Carius method of estimation of halogen,$0.15 \ g$ of an organic compound gave $0.12 \ g$ of $AgBr$. Find out the percentage of bromine in the compound.
