In the estimation of nitrogen by Kjeldah...

In the estimation of nitrogen by Kjeldahl's method, 2.8 gm of an organic compound required 20 millimole of `H_(2)SO_(4)` for the complete neutralization of `NH_(3)` gas evolved. The percentage of nitrogen in the sample is:

A

0.2

B

0.1

C

0.4

D

0.3

Text Solution

Verified by Experts

The correct Answer is:
A
Kjeldhars method % `N=(1.4 xx "meq of" H_(2)SO_(4))/("mass of organic compound")=(1.4 xx 20 xx 2)/(2.8)=20%`
