45 Pressure-kPa 40 35 30 Bubble curve 25 20 15 10 0.6 1.2 0.4 0.2 0.8 Molar concentration of N₂ A mixture diagram of Oxygen (O₂) and Nitrogen (N₂) is shown in Figure 1. Answer the followings: molar fraction X XM XXM+YXN - where M is the molar c. The calculation of Nitrogen (N₂) mass fraction is given by mass of Nitrogen (N₂ = 28 g / mol) and N is the molar mass of Oxygen (O₂ = 32 g/mol). X and Y are the molar fraction of Nitrogen (N₂) and Oxygen (O₂) respectively in either liquid or vapour phase. Calculate the mass fraction of Nitrogen (N₂) in the vapour phase at 20 kPa.
