Question

during nitrogen estimation of an organic compound by kjeldahls method the ammonia evolved by 0.5 gram of the compound neutralizes 10 ml of 1 molar H2 S o4 calculate the percentage of Nitrogen in the compound.I KNOW ANSWER PLZ GIVE STEP BY STEP EXPLAINATION....​

Answer 1

Answer:

Mass of the organic compound taken = 0.5g

Volume of 1MH2 SO4 required for nutralising ammonia = 10ml

10ml of 1MH2 SO4 = 20ml of 1MNH3

Now 1000ml of 1M ammonia contains 14 g nitrogen

20ml of 1M ammonia would contain

= 14/100 × 20g of nitrogen

Percentage of nitrogen =14×20/1000×1000/0.5 = 56.0%
