In the Carius method for the estimation of halogen,$0.172 \ g$ of an organic compound showed the presence of $0.08 \ g$ of bromine. Which of these is the correct structure of the compound?

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?

Following Kjeldahl's method,$1 \ g$ of organic compound released ammonia,which neutralized $10 \ mL$ of $2 \ M \ H_2SO_4$. The percentage of nitrogen in the compound is . . . . . . $\%$.

During the estimation of nitrogen present in an organic compound by the Kjeldahl method,the ammonia evolved from $0.5 \ g$ of the compound neutralized $10 \ mL$ of $1 \ M$ $H_{2}SO_{4}$. Find the percentage of nitrogen in the compound. (in $\%$)

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