0.28 g of nitrogenous compound was subjected to Kjeldahl's process to produce 0.17 g of `NH_(3)` . The percentage of nitrogen in the organic compound is

A

5

B

2

C

50

D

80

Text Solution

Verified by Experts

The correct Answer is:
C
0.17 g `NH_(3)` will contains `(14/17 xx0.17)` g of nitrogen , i.e., 0.14 g of nitrogen
% Nitrogen =`("Mass of nitrogen ")/("Mass of compound ")xx100=0.14/0.28xx100=50%`
