Question
$1.2\text{ g}$ of an organic compound on Kjeldahlization liberates ammonia which directly consumes $30\text{ cm}^3$ of $1\text{ N } HCl$. The percentage of nitrogen in the compound is:
Answer: C
💡 Solution & Explanation
Using the direct percentage formula: $\%N = \frac{1.4 \times N_{\text{acid}} \times V_{\text{acid}}}{Mass} = \frac{1.4 \times 1 \times 30}{1.2} = 35.0\%$.
