0.25 g of an organic compound on Kjeldahi's analysis gave enough ammonia to just neutralize `10 cm^3` of 0.5 M `H_2SO_4` The percentage of nitrogen in the compound is

A

28

B

56

14

D

112

Text Solution

Verified by Experts

The correct Answer is:
B
From Kjeldahl.s method
Per cent of nitrogen `=(1.4 times N times V)/W`
`=(1.4 times 0.5 times 2 times 10)/0.25`
