Question

solution. Calculate % of nitrogen in organic compound.
1.25 gm of organic compound under kjeldhalism evolve NH, gas, which is passed in 100 ml, 1 N
H,SO, solution then vol. made up to 500 ml, 25 ml of this solution required 100 ml, 0.01 N, NaOH​

Answer 1

Answer:

Explanation:

25 ml requires 1

500 ml requires 20

And initially passed through 100 equivalent

Equivalent of ammonia = 80

Moles=0.08

Weight = 1.36 gm

Percentage of ammonia = 14/17 × 1.36/1.25×100

=89.6
