In Duma's method of estimation of nitrogen, 0.1840 g of an organic compound gave 30 mL of nitrogen collected at 287 K and 758 mm of Hg pressure. The percentage composition of nitrogen in the compound is __________. (Round off to the Nearest Integer). [Given : Aqueous tension at 287 K = 14 mm of Hg]
Your Input ________
Correct Answer is 19
Aqueous tension at 287 K = 14 mm of Hg.
Hence actual pressure = (758 – 14)
= 744 mm of Hg.
