$0.2 \ g$ of an organic compound was subjected to estimation of nitrogen by Dumas method in which volume of $N_2$ evolved (at $STP$) was found to be $22.400 \ mL$. The percentage of nitrogen in the compound is $.......$. [nearest integer] (Given: Molar mass of $N_2$ is $28 \ g \ mol^{-1}$. Molar volume of $N_2$ at $STP$ : $22.4 \ L \ mol^{-1}$ )

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:
