In the Dumas method,$1 \ g$ of an organic compound gives $50 \ mL$ of $N_2$ gas at $300 \ K$ and $740 \ mm \ Hg$ pressure. If the aqueous tension at $300 \ K$ is $15 \ mm \ Hg$,what is the percentage of nitrogen in the compound?

What are the advantages of the $CHN$ elemental analysis method?

Which one of the following methods can be used to find out the percentage composition of halogen present in an organic compound?

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

Which method is used for the quantitative estimation of nitrogen in an organic compound?

$1.2 \ g$ of an organic compound on Kjeldahlization liberates ammonia which consumes $30 \ cm^3$ of $1 \ N \ HCl$. The percentage of nitrogen in the organic compound is:
