The solubility of oxygen from the air is 2.67 × 10-4 m at sea level and 25°c what is the solubility of o2 in a mountain lake at an elevation of 12,000 ft where the atmospheric pressure is 0.657 atm? assume the temperature is 25°c, and that the percent mole of o2 in air is 20.9% at both 12,000 ft and at sea level.

Describe different biomes. what are some adaptations that organisms (plants or animals) must have to live in each biome?

The air in an automobile tire with a volume of 2.60 ft3 is at 70°f and 21 psig. determine the amount of air that must be added to raise the pressure to the recommended value of 30 psig. assume the atmospheric pressure to be 14.6 psia and the temperature and the volume to remain constant. the gas constant of air is ru = 53.34ft⋅lbflbm⋅r(1 psia144 lbf/ft2) = 0.3704 psia⋅ft3lbm⋅r the amount of air that must be added to raise the pressure is lbm
