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.
On a particular summer day, the temperature is 30.0°C and the relative humidity is 77.0% (which means that the partial pressure of water vapor in the ambient air is 77.0% of the equilibrium vapor pressure of water). A sample of this air is placed in a 1.00 L flask, which is then closed and cooled to 5.00'C. A: 30.0°C, the vapor pressure of water is 31.8 mmHg. and at 5.00°C is 6.50 mmHg. What is the mass (in grams) of...
15. 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 56% and its temperature is 70°F, how many grams of water are present in a room measuring 15 ft x 10 ft x 11 ft? The vapor pressure of water at 68 °F is 17.54 torr. Show your work 15. The...

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...
Be sure to answer all parts. A person inhales air richer in O2 and exhales air richer in CO2 and water vapor. During each hour of sleep, a person exhales a total of about 300. L of this CO2−enriched and H2O-enriched air. (a) If the partial pressures of CO2 and H2O in exhaled air are each 28.3 torr at 37.0°C, calculate the masses of CO2 and of H2O exhaled in 1 h of sleep. -g CO2 -g H2O (b) How...
