Question

1. Fresh air containing 4.00 mole % water vapor is to be cooled and dehumidified to a water
content of 1.70 mole% H20. A stream of fresh air is combined with a recycle stream of
previously dehumidified air and passed through the cooler. The blended stream entering
the unit contains 2.30 mole% H2O. In the air conditioner, some of the water in the feed
stream is condensed and removed as liquid. A fraction of the humidified air delivered to
the cooler is recycled and the remainder is delivered to a room. Taking 100 mole of
dehumidified air delivered to the room as a basis of calculation; calculate the moles of
fresh feed, moles of water condensed, and moles of dehumidified air recycled.
Recycle stream (R)
Fresh air (F)
Dehumidifier
→ 100 moles
Water removed (Y)

If 1000 L of gasoline has spilled into the street (MW=117 g/mol, density=0.7 g/mL which is true for octane) then firefighters add a lot of a material that dissolves into it that reduces the vapor pressure (liquid octane doesn’t burn, only the vapors). The firefighters put 500 kg of a material into the gasoline and reduced its vapor pressure from the pure partial pressure of 10.0 kPa down to 8.0 kPa. What is the molecular weight of the material that was added? (hint: use Raoult’s Law, which relates changes in pressure to the mol fractions.
