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