Solution

Mass of organic compound= $0.5 g$

Volume of $1 M$ $H_{2} S O_{4}$ required= $10 m l$

$∴ 10 m l$ of $1 M$ $H_{2} S O_{4} = 20 m l$ of $1 M$ $N H_{3}$

Now $1000 m l$ of $1 M$ $N H_{3}$ contains $14 g$ $N$

$∴ 20 m l$ of $1 M$ $N H_{3}$ would contain= $\frac{14}{1000} \times 20$

$∴$ Percentage of $N = \frac{14 \times 20}{1000} \times \frac{100}{0.5} = 56$ %
