$58 \ mL$ of $\frac{N}{5} \ H_2SO_4$ are used to neutralize ammonia given by $1 \ g$ of an organic compound. The percentage of nitrogen in the compound is:

Which of the following substances cannot be analyzed using the Kjeldahl method for the estimation of nitrogen?

$29.5 \ mg$ of an organic compound containing nitrogen was digested according to Kjeldahl's method and the evolved ammonia was absorbed in $20 \ mL$ of $0.1 \ M \ HCl$ solution. The excess of the acid required $15 \ mL$ of $0.1 \ M \ NaOH$ solution for complete neutralization. The percentage of nitrogen in the compound is $..... \%$.

In the estimation of $C$ and $H$ by Liebig's method,is $H_2O$ absorbed before $CO_2$? Why?

In the Carius method,a halogen-containing organic compound is heated with fuming nitric acid in the presence of:

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 $80 \ g \ mol^{-1}$)
