During estimation of nitrogen in the organic compound by Kjeldahl's method, the ammonia evolved from 0.5 g of the compound in Kjeldahl's estimation of nitrogen, neutralised 10 mL of 1MH2SO41 \mathrm{M} \mathrm{H}_2 \mathrm{SO}_4. Find out the percentage of nitrogen in the compound.

Options

  1. A14%14 \%
  2. B28%28 \%
  3. C56%56 \%
  4. D68%68 \%

Correct answer

C. 56%56 \%

Step-by-step solution

1 M of 10mLH2SO4=1M10 \mathrm{mLH}_2 \mathrm{SO}_4=1 \mathrm{M} of 20mLNH320 \mathrm{mLNH}_3 1000 mL of 1 M ammonia contains =14 g=14 \mathrm{~g} nitrogen 20 mL of 1MNH31 \mathrm{M} \mathrm{NH}_3 contains 20 mL of 1MNH31 \mathrm{M} \mathrm{NH}_3 contains =14×201000 g=\frac{14 \times 20}{1000} \mathrm{~g} nitrogen %\% age of nitrogen =14×20×1001000×0.5=56.0%=\frac{14 \times 20 \times 100}{1000 \times 0.5}=56.0 \%
