1. (25 pts) Ethyl alcohol vapors and air are mixed. The partial pressure of the ethyl alcohol is 0.550kPa. The pressure and temperature of the ideal gas mixture are 96.0kPa and 25.0C respectively. Calculate the mole fraction (PPM), the mass concentration (mg/m3) and the molar concentration (mol/m3) of the ethyl alcohol. 2. (25 pts) Sulfur doxide (SO2) is mixed with air and is flowing in a duct. The molar concentration of the SO2 in the duct is 10.0mol/m3. The total volume flow rate of the air and SO2 mixture is 0.020m3/s. (a) Estimate the mass flow rate of SO2 in the duct (in units of g/s and also in units of lbm/min ). (b) If the duct is vented to the atmosphere with no pollution control device, estimate how many tons of SO2 are discharged into the atmosphere in a year assuming that the plant runs 16 hours per day, 6 days per week ( 1 ton mass =2000lbm). 3. (25 pts) A mixture of air and water vapor is at 40C in air of atmospheric pressure 90.0kPa. The mole fraction of the water vapor is 32,000 PPM. (a) Calculate the relative humidity of this moist air as a percentage to three significant digits. (b) Calculate the partial pressures of both the water vapor and the air in units of kPa to three significant digits
