The mass fractions of a mixture of gases are 10 percent nitrogen, 3 percent helium, 55 percent methane, and 32 percent ethane. Determine the mole fractions of each constituent, the mixture’s apparent molecular weight, the partial pressure of each constituent when the mixture pressure is 1200 kPa, and the apparent specific heats of the mixture when the mixture is at the room temperature. The universal gas constant is Ru = 8.314 kJ/kmol·K. Use the table containing the molar mass, gas constant, and critical-point properties and the table containing the ideal-gas specific heats of various common gases.
