5. Under normal physiological conditions, hemoglobin is half saturated with O2 at 26 torr, and the Hill coefficient nn = 2.8. What is the degree of saturation when the partial pressure of O2 in the tissue capillaries falls to 33 torr during gentle walking? A. 0.34 B. 0.41 C. 0.56 D. 0.66 E. 1.00
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 .
Calculate the partial pressure of O2 (P02, mm Hg) in dry air in Arcata (sea level- assume atmospheric pressure of 760 mm Hg). Arcata air never gets fully dry. Assume 90% humidity at 15°C (saturated water vapor pressure at 15°C=12.8 mm Hg) and calculated the actual partial pressure of O2 in Arcata air
Assume that the partial pressure of sulfur dioxide, PSO2, is equal to the partial pressure of dihydrogen sulfide, PH2S, and therefore PSO2=PH2S. If the vapor pressure of water is 28 torr , calculate the equilibrium partial pressure of SO2 (PSO2) in the system at 298 K.
Calculate the solubility of oxygen in water at a partial pressure of O2 of 343 torr at 25°C. The Henry's Law constant for oxygen in water is 1.28 x 10 mol/(atm L). mol/L
5) Oxygen gas is collected over water. The total pressure (the O2 pressure + the water vapor pressure) is 765 torr. The temperature of the water is such that the water vapor pressure is 38 torr. What is the partial pressure of the oxygen gas in torr?
Assume all gases in this problem are ideal (a) If the partial pressure of water vapor is 31.8 torr, what is the dew point (in °C)? (760 torr- 1 atm 101,325 Pa) oC (b) On a warm day when the air temperature is 25°C and the dew point is 18°C, what are the partial pressure of the water in the air (in Pa) and the relative humidity? partial pressure R.H. Pa
Assume that the partial pressure of sulfur dioxide, PSO2 , is equal to the partial pressure of dihydrogen sulfide, PH2S , and therefore PSO2=PH2S. If the vaporpressure of water is 27 torr, calculate the equilibrium partial pressure of SO2 (PSO2) in the system at 298 K. Express the pressure in atmospheres to two significantfigures.PSO2= __ atmIn part A, Kp= 8*10^15:( I keep getting it wrong.
