In Kjeldahl’s method,the nitrogen present in the organic compound is quantitatively converted into

When $1 \ g$ of compound $(X)$ is subjected to Kjeldahl's method for the estimation of nitrogen, $15 \ mL$ of $1 \ M$ $H_2SO_4$ was neutralized by the ammonia evolved. The percentage of nitrogen in compound $(X)$ is:

In the Dumas method for the estimation of nitrogen,$0.388 \ g$ of an organic compound yielded $1.31 \ mL$ of $N_2$ gas collected at $293 \ K$ temperature and $746 \ mm$ pressure. Calculate the percentage of nitrogen in the compound. (Aqueous tension at $293 \ K = 6 \ mm$). (in $\%$)

$0.2595 \ g$ of an organic substance in a quantitative analysis yielded $0.35 \ g$ of barium sulphate. The percentage of sulphur in the substance is $...$

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

The reaction of $Q$ with $PhSNa$ yields an organic compound (major product) that gives a positive Carius test on treatment with $Na_2O_2$ followed by the addition of $BaCl_2$. The correct option$(s)$ for $Q$ is (are):
