0.50 gm of an organic compound was treated according to Kjeldahl's meghod. The ammonia evolved was absorbed in 50 ml of 0.5 `MH_2SO_4`. The residual acid required 60 ml of `(M)/(2)NaOH` solution. Find the percentage of nitrogen in the compound.

Explanation

To find the percentage of nitrogen in the organic compound using the Kjeldahl method, follow these steps:

### Step 1: Calculate the equivalents of H₂SO₄
The amount of H₂SO₄ used is given as 50 mL of 0.5 M solution.

\[ \text{Equivalents of H₂SO₄} = \text{Volume (L)} \times \text{Molarity (M)} \times \text{n-factor} \]
