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

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 . . . . . . $\%$.

$2.18 \ g$ of an organic compound containing sulphur produces $0.12 \ g$ of $BaSO_4$. The percentage of sulphur in the compound is?

For the estimation of nitrogen,$1.4 \ g$ of an organic compound was digested by Kjeldahl method and the evolved ammonia was absorbed in $60 \ mL$ of $\frac{M}{10}$ sulphuric acid. The unreacted acid required $20 \ mL$ of $\frac{M}{10}$ sodium hydroxide for complete neutralization. The percentage of nitrogen in the compound is .....$\%$

What is $CHN$ analysis in organic estimation?

$0.8 \ g$ of an organic compound was analysed by Kjeldahl's method for the estimation of nitrogen. If the percentage of nitrogen in the compound was found to be $42 \ \%$,then $.... \ mL$ of $1 \ M$ $H_2SO_4$ would have been neutralized by the ammonia evolved during the analysis.
