4. (25 pts) The following data are available for the viscosities of mixtures of hydrogen (M = 2.016 g/mol) and Freon-12 (dichlorodifluoromethane, CC12F2, M = 120.92 g/mol) at 25 °C and 1 atm: Mole fraction of H2 0.00 0.25 0.50 0.75 1.00 μx 106 (P = poise) 124 128.1 131.9 135.1 88.4 a. Use the viscosities of the pure components to calculate the viscosity of a 25 mol% H2 and 75 mol% Freon-12 gas mixture, expressed in mPa·s. b. Compare these values to the observed value in the table above.
