Solution Summary

Saturated vapor pressure in a room is given. The mass of water vapor in the room is calculated.

Solution Preview

Solution:
The water vapors in air behaves as ideal gas and therefore we may consider the moist air as a mixture of two ideal gases, where total pressure is the sum of the pressure exerted by the components individually. The saturated vapor ...
