A volume of 18.0 L contains a mixture of 0.250 mole N2 , 0.250 mole O2 , and an unknown quantity of He. The temperature of the mixture is 0 ∘C , and the total pressure is 1.00 atm...
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.)
The partial pressure of O2 in air at sea level is 0.21 atm. The solubility of O2 in water at 20 ∘C , at 1 atm gas pressure, is 1.38×10−3 M. Using Henry's law and the data in the introduction, calculate the molar concentration of O2 in the surface water of a mountain lake saturated with air at 20 ∘C and an atmospheric pressure of 660 torr .
Use Henry's law and the solubilities given below to calculate the total volume of nitrogen and oxygen gas that should bubble out of 1.6 L of water upon warming from 25 ∘C to 50 ∘C. Assume that the water is initially saturated with nitrogen and oxygen gas at 25 ∘C and a total pressure of 1.0 atm. Assume that the gas bubbles out at a temperature of 50 ∘C. The solubility of oxygen gas at 50 ∘C is 27.8 mg/L...
Item 26 Review l Constants i Periodic Table Learning Goal: To use partial pressure in gas law calculations In a mixture of gases, the total pressure of the gas mixture is equal to the sum of the partial pressures of the individual gases. For example, if you have a mixture of helium at 2 atm and argon at 4 atm, then the total pressure of the gas inside the cylinder is 6 atm . (Figure 1) Similarly, if you know...

What is this asking? 2) Given the partial pressure of 3 gases in a container of a given volume and temperature, what is the total pressure in the same units? What is the mole fraction of one of the specific gases? If the total pressure were changed, what would the new value for partial pressure of one of the gases (different from the gas asked in the previous part)? What is the value for the new volume?
