A 0.166 g sample of an organic compound was digested with cone. H 2 SO 4 and then distilled with NaOH. The ammonia gas evolved was passed through 50.0 mL of 0.5 N H 2 SO 4 . The used acid required 30.0 mL of 0.25 N NaOH for complete neutralization. The mass percentage of nitrogen in the organic compound is____.
Text Solution
Verified by ExpertsThe correct answer is:
63
(63)
m eq of NaOH used = 30 x0.25
m eq of H 2 SO 4 taken = 50 x 0.5
meq of H 2 SO 4 used
= 50 x 0.25 x30 x0.25 = 17.5 m mol of NH 3
(Not possible)
