The relative humidity of air equals the ratio of the partial pressure of water in the air to the equilibrium vapor pressure of water at the same temperature times 100%. If the relative humidity of the air is 58% and its temperature is 68 oF , how many moles of water are present in a room measuring 12 ft x 10 ft x 8 ft? The vapor pressure of water at 68 oF is 17.54 torr.

0.75 L bottle is cleaned, dried, and closed in a room where the air is 24°C and 38% relative humidity (that is, the water vapor in the air is 0.38 of the equilibrium vapor pressure at 24°C). The bottle is brought outside and stored at 0.0°C. (a) What mass of water condenses inside the bottle? (b) Would water condense at 10°C?

1. (relative humidity) The partial pressure of water vapor in air is usually less than the equilibrium vapor pressure (or saturation pressure) at the ambient temperature; this is why a cup of water will spontaneously evaporate. The ratio of the partial pressure of water vapor to the equilibrium vapor pressure (at the same temperature) is called the relative humidity. Saturated air, at 100% relative humidity, would be in equilibrium with a cup of liquid water. The saturation pressure depends strongly...
