`0.2033g` of an organic compound in Dumas method gave `31.7mL` of moist `N_(2)` at `14^(@)C` and `758mm` pressure. Percentage of `N_(2)` in the compound is (Aq.tension at `14^(@)C=14mm)`

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)

0.2325 g of an organic compound was analysed for nitrogen by Duma's method. 31.7 mL of moist nitrogen was collected at 25°C and 755.8 mm pressure. Calculate the percentage of nitrogen in the sample (aq. tension of water at 25°C and 23.8 mm).
