Describe Duma's method for the estimation of nitrogen in an organic compound.

In dumas method for the estimation of nitrogen in an organic compound,nitrogen is determined in the form of:

In Kjeldahl's method for quantitative estimation of nitrogen in an organic compound, ammonia obtained from 1.25 g of the compound was neutralised by 40 ml of 0.5 M H_2SO_4 The percentage of nitrogen in the organic compound is

In Duma's method for estimation of nitrogen 0.4 gm of an organic compound gave 60 ml of nitrogen collected at 300 K and 715 mm pressure. Calculate the percentage composition of nitrogen in the compound : (Aqueous tension at 300 K=20 mm)

In Duma's method for estimation of nitrogen. 0.25 g of an organic compound gave 40mL of nitrogen collected at 300K temperature of 725 mm pressure. If the aqueous tension at 300K is 25 mm , the percentage of nitrogen in the compound is

In the Duma's method for estimating nitrogen in an organic compound, the gas finally collected is

In Dumas’ method for estimation of nitrogen, 0.3g of an organic compound gave 50mL of nitrogen collected at 300K temperature and 715mm pressure. Calculate the percentage composition of nitrogen in the compound. (Aqueous tension at 300K=15 mm)

In the Dumas method for the estimation of nitrogen , 0.0237 grams of an organic compound gave 2.21 mL of nitrogen at 754.32 mm of Hg pressrue at 18^(@)C . (Aquesous tension at 18^(@)C is 15.4mm of Hg ). Therefore the percentage of nitrogen in the compound is

In the Lassaigne's test for the detection of nitrogen in an organic compound, the appearance of blue coloured compound is due to

In Duma's method for quantitative estimation of nitrogen, 0.5 g of an organic compound gave 100 ml of nitrogen collected at 27°C temperature and 680 mm of Hg pressure. What is the percentage composition of nitrogen in the sample? [Given aqueous tension at 27°C = 20mm Hg]

In Dumas' method of estimation of nitrogen 0.35 g of an organic compound gave 55mL of nitrogen collected at 300K temperature and 715 mm pressure. The percentage composition of nitrogen in the compound would be : ( Aqueous tension at 300K =15 mm)
