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

10) (10pts) A cold pack consists of a small inner bag that contains water inside another larger bag that contains solid ammonium nitrate. When a cold pack is needed, the inner bag is broken and the water and ammonium nitrate are shaken together to dissolve the solid. If the inner bag contains 117 mL of water (density 1.00 g/mL), how many grams of ammonium nitrate must the outer bag contain to lower the temperature of the water from 23.0 °C...
