A wide 2000 m3 laboratory has a ventilation system. This may be designed to eliminate toxicants from the laboratory to the outside so the ventilation system maintains safe , comfortable and respiratory conditions for all laboratory users and decreases the risk of dangerous pollutants. At a volumetric fluctuation rate of 900 m3 / min at 20 °C and 1 atm, the ventilated air is discharged, which is often to be known as a lab temperature and pressure. The lab was...
8. What is the difference in blood oxygen concentration between a person at sea level where the air pressure is 1.0 atm and the top of K2, where the total air pressure is 34.7 kPa? (You can assume the mole fraction of oxygen in air remains constant at 0.2
1. What is the difference in blood oxygen concentration between a person at sea level where the air pressure is 1.0 atm and the top of K2, where the total air pressure is 34.7 kPa? (You can assume the mole fraction of oxygen in air remains constant at 0.21 (or 21% of the total air pressure is oxygen), the temperature is 37 C, and that the solubility of oxygen in blood at 37 C is approximately 1.0 x 10-3 mol/L-atm.)

Unit conversion. (10 pts) Convert a concentration of 5.62 ´1013 molecules/cm 3 to the ppb scale. Assume 25° C and 1.0 atm total air pressure. Convert a concentration of 6.0 ´1014 molecules/cm 3 to the moles per liter (molarity) scale. Assume 27.5° C and 0.99 atm total air pressure. Convert a concentration of 36.5 ppb of ozone, O3, into the number of molecules/cm3. Assume the air mass temperature is 25.3° C and its total pressure is 1.05 atm. Convert a...

A home in Florida loses electricity when a hurricane makes landfall. The hurricane is slow- moving and takes several days to move through the area. In order to power a fan and a refrigerator, the homeowner starts a generator in his garage, which has a length of 6 m, a width of 5.5 m, and a floor-to-ceiling height of 2.5 m. The garage door is closed due to the hurricane and the ventilation rate is 0.60 air changes per hour...
