1.	0.30g of an organic compound gave 50 cc of nitrogen collected at 300K and 715 mm pressure in Duma's method. Calculate the percentage of nitrogen in the compound.(Vapour pressure of water at 300K is 15 mm).
Answer» given organic compound = 0.30 gWe have to calculate the volume of NITROGEN at N.T.PGiven: = 50 ml = 715 - 15 = 700 mm = 300 KAt NTP: Calculate the percentage of nitrogen:22400 ml of nitrogen at N.T.P WEIGHT = 28 G
