In the Carius method, $0.2425 \ g$ of an organic compound gave $0.5253 \ g$ of silver chloride. The percentage of chlorine in the organic compound is: (in $\%$)

Discuss the Dumas method and its principles for the estimation of $N$ present in an organic compound.

In Dumas method for estimation of nitrogen,$0.3 \ g$ of an organic compound gave $41.9 \ mL$ of nitrogen gas at $\text{STP}$. What is the percentage of nitrogen (in $.5$)?

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

In the Carius method,$0.099 \, g$ of an organic compound gave $0.287 \, g$ of $AgCl$. The percentage of chlorine in the compound is:

$0.25 \ g$ of an organic compound containing chlorine gave $0.40 \ g$ of silver chloride in Carius estimation. The percentage of chlorine present in the compound is $.....$ [in nearest integer].
(Given: Molar mass of $Ag$ is $108 \ g \ mol^{-1}$ and that of $Cl$ is $35.5 \ g \ mol^{-1}$)
