8. A vessel contains a mixture of H, and N, gas. The density of this gas mixture is 0.2 g L-! at 300K and I atm. Assuming that both the gases behave ideally, the mole fraction ofN, (g) in the vessel is (Final answer should be rounded off to two decimal places) [Given: R = 0.082 L atm mol" K", atomic wt. of hydrogen = 1.0 and atomic wt. of nitrogen = JAM 20171 14.0]
