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 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)

In Duma's method,the gas which is collected in Nitromer is 0.35 g of an organic compound gave 55 mL of nitrogen collected at 300 K temperature and 715 mm pressure .The precentage composition of nitrogen in the compound would be : (Aqueous tension at 300 K= 15 mm)
