please solve these two questions!!

Q.2. In a device to produce potable water, humid air at 90F,29.7 in Hg, and 95% relative humidity is cooled to 40F at constant pressure. What volumetric flow rate of air into the cooler (ft3/min) is required to provide 10.0gal/min of condensed water? Use Raoult's law for equilibrium. Vapor pressure of water in Table B3 in Textbook. Density of water =62.43lbm/ft3. Relative Saturation or Relative Humidity: sr or hr=pi(T)pi100% Q.3. A vapor stream that is 65 mole\% styrene and 35 mole\% toluene is in equilibrium with a liquid mixture of the same two species. The pressure in the system is 150mmHg absolute. Use Raoult's law to estimate the composition of the liquid and the system temperature. Use Antoine equation for vapor pressures (p in mmHg,T in C) with the following parameters: (For Styrene: A=6.92409,B=1420,C=206, for Toluene: A=6.95334,B=1343.943,C=219.377 )
