% N =(1.4( N 1 V 1)/ text massof organic compound ) % N =(1.4(2.5 × 2 × 2)/0.25)=56

Q. While estimating the nitrogen present in an organic compound by Kjeldahl's method, the ammonia evolved from $0.25 g$ of the compound neutralized $2.5 m L$ of $2 M H_{2} S O_{4}$ . The percentage of nitrogen present in organic compound is _____

$% N = \frac{1.4 ( N _{1} V _{1} )}{massof organic compound}$
$% N = \frac{1.4 ( 2.5 \times 2 \times 2 )}{0.25} = 56$

Q. While estimating the nitrogen present in an organic compound by Kjeldahl's method, the ammonia evolved from 0.25g of the compound neutralized 2.5mL of 2MH2​SO4​. The percentage of nitrogen present in organic compound is _____

%N= massof organic compound 1.4(N1​V1​)​ %N=0.251.4(2.5×2×2)​=56
