Question

0 31g of N-containing compound on reaction with NaOH gave
NH3 which required 100mL of 0 1N HCl hence,% of N
is:
(a)45 16%
(b)90 32%
(c)22 58%
(d)11 29%

Geetha · Accepted Answer

As per Kjeldahl method% of N= 1
4 × Volume of the acid × Strength of the acidWeight of organic compound   = 1
4 × 100 × 0 10
31  = 45
16 %Thus option a is correct

0.31g of N-containing compound on reaction with NaOH gave NH3 which required 100mL of 0.1N HCl.hence,% of N is: (a)45.16% (b)90.32% (c)22.58% (d)11.29%
