In Dumas' method for estimation of nitrogen 1 g of an organic compound gave 150 mL of nitrogen collected at 300 K temperature and 900 mm Hg pressure. The percentage composition of nitrogen in the compound is _____ % (nearest integer). (Aqueous tension at 300 ~K =15 ~mm Hg )
Correct answer
0
Step-by-step solution
Partial pressure of N ₂=(900-15)=885 ~mm Hg Mole of N ₂= ( 885 760 0.15 ) (0.0821 300) =0.0071 Moles % of nitrogen in organic compound aligned & = (0.0071 28) 1 10 & =19.85 % aligned
