An adult inhales approximately 12 times per minute, taking in about 500 ml of air with each inhalation. oxygen and carbon dioxide are exchanged in the lungs, but there is essentially no exchange of nitrogen. the exhaled air has a mole fraction of nitrogen of 0.75 and is saturated with water vapor at body temperature, 37°c. if ambient conditions are 25°c, 1 atm, and 50% relative humidity, what volume of liquid water (ml) would have to be consumed over a two-hour period to replace the water loss from breathing? how much would have to be consumed if the person is on an airplane where the temperature, pressure, and relative humidity are respectively 25°c, 1 atm, and 10%?
