In Carius method of estimation of halogen,$0.25 \ g$ of an organic compound gave $0.15 \ g$ of silver bromide $(AgBr)$. The percentage of Bromine in the organic compound is $.......... \times 10^{-1} \%$ ($Nearest$ integer). (Given: Molar mass of $Ag$ is $108 \ g \ mol^{-1}$ and $Br$ is $80 \ g \ mol^{-1}$)

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 $15 \ mm$).

For the estimation of nitrogen,$1.4 \ g$ of an organic compound was digested by Kjeldahl method and the evolved ammonia was absorbed in $60 \ mL$ of $\frac{M}{10}$ sulphuric acid. The unreacted acid required $20 \ mL$ of $\frac{M}{10}$ sodium hydroxide for complete neutralization. The percentage of nitrogen in the compound is .....$\%$

Given below are two statements :
Statement $I$ : Kjeldahl method is applicable to estimate nitrogen in pyridine.
Statement $II$ : The nitrogen present in pyridine can easily be converted into ammonium sulphate in Kjeldahl method.
In the light of the above statements,choose the correct answer from the options given below.

In the Carius method for the estimation of halogens,$0.15 \, g$ of an organic compound gave $0.12 \, g$ of $AgBr$. Find the percentage of bromine in the compound. (in $\%$)

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 $Hg$ ]
