A mixture diagram of Oxygen (O₂) and Nitrogen (N₂) is shown in Figure 1. Answer the followings: a. What is the molar fraction of Nitrogen (N₂ = X) in liquid phase at the pressure of 25 kPa? (7.5 marks) b. What is the molar fraction of Oxygen (O₂ = Ỹ) in liquid phase at the pressure of 25 kPa? (7.5 marks) molar fraction X XM XxM+YxN c. The calculation of Nitrogen (N₂) mass fraction is given by where M is the molar 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. (5 marks)
