Physics Question Time!

penkSo I'm running a dehumidifier in my basement due to the ridiculous humidity levels in the last week or so. In an hour of running, it extracted about a half gallon of water from the air.
Which got me thinking.
Given:
1) Basement air volume of approximately 4500 cubic feet (20x30 basement with an 7.5' ceiling)
2) A relative humidity of between 50 and 60% (based on current forecasts. It's occasonally spiking up to 80%)
3) Ambient temperature at the start of this process at 84 degrees fahrenheit. Current indoor temperature is 76 degrees.
How much water is actually IN the air now?
If I cool down to 72 degrees, how much water will be extracted - ie, how often do I have to change the tank out?
I've been S'ingTFW, and have gotten a lot of physics chattering, but haven't been able to suss out the actual values.
Any ideas?
