(C) The formula for the percentage of nitrogen in the Kjeldahl method is: $\% \ N = \frac{1.4 	imes 	ext{Normality of acid} 	imes 	ext{Volume of acid in mL}}{	ext{Mass of organic compound in g}}$.Given:Normality of $H_2SO_4 = \frac{1}{5} \ N = 0.2 \ N$.Volume of $H_2SO_4 = 58 \ mL$.Mass of organic compound = $1 \ g$.Substituting the values:$\% \ N = \frac{1.4 	imes 0.2 	imes 58}{1} = 16.24 \%$.Rounding to the nearest option,the percentage of nitrogen is $16.2 \%$.

$58 \ mL$ of $\frac{N}{5} \ H_2SO_4$ are used to neutralize ammonia given by $1 \ g$ of an organic compound. The percentage of nitrogen in the compound is:
