A container holding 10.0 kg of water is placed in a closed space station containing an air volume of 2500 m3 of completely dry air. Eventually the water either all evaporates or comes into vapor pressure equilibrium with the air which is kept at a steady 22.0°C. What is the final humidity?

Liquid water in a closed container at 25 degrees C is in equilibrium with water vapor at a pressure of 0.0313 atmospheres. Consider a puddle on a sidewalk at 25 degrees C. If the relative humidity is 38% (i.e., the H2O(g) partial pressure is 0.012 atmospheres) what is the free energy change for evaporation of water from the puddle?

A container filled with 45 kg of liquid water at 95°C is placed in a 90 m3 room that is initially at 12°C. Thermal equilibrium is established after a while as a result of heat transfer between the water and the air in the room. Using constant specific heats at room temperature, determine a) the final equilibrium temperature b) the amount of heat transfer between the water and the air in the room c) the entropy generation /3] I /8]...

Problem2 (a) Suppose outside temperature is 55 °F while the temperature inside a building is 72 F. The building is heated but not air conditioned, so the partial pressure of water vapor is the same both inside and outside the building. Finally, suppose the dew point outside is 40°F What is the dew point inside? What are the relative humidities inside and outside the building? (We are most comfortable if relative humidity is between 30% and 50%-This question shows why...

i dont understand why the molecular weight i calculated
(42.012 g/mol) for my unknown liquid (acetone) is less than the
actual molecular weight (58.08 g/mol). what errors could i have
made in my lab that would account for the difference.

4. Construct a flow chart describing the separation of the mixture and the isolation of each compound in this experiment. A commonly used method of separating a mixture of organic compounds is known as liquid-liquid extraction. Most reactions of organic compounds require extraction at some stage of product purification. In this experiment you will use extraction...
