0.59 g of an organic substance when treated with caustic soda evolved ammonia ,Which requried 20 c.c of N/2 sulphuric acid of neutralization
The percentage of nitrogen is

Options

A. 0.4
B. `53.6%`
C. `63.6%`
D. 0.2373

Answer

D

Explanation

Vol. of `H_(2)SO_(4)` taken =20 cc of N/2 `H_(2)SO_(4)`
% age of ` N=(1.4NV)/(W) `
N=Normality of acid used
V = Vol.of acid used
W=Wt.of organic compound
`% age of N = (1.4xx1xx20)/(2xx0.59)= 23.72%`
