Temperature when the air is full of water vapor

I think this is correct ( sorry if is not)
This temperature where the change of state occurs is called the dew point. For air containing 3.368 g/kg of water vapor, the dew point is 30 degrees F; for air containing 10.699 g/kg of water vapor, the dew point is 60 degrees F; and for air containing 30.052 g/kg of water vapor, the dew point is 90 degrees F.
hope this helps!
