Calculate the atmospheric pressure at the tropopause (~15 km) and calculate the grams of oxygen in 1m³ at this altitude. P₀ = pressure at sea level = 101,325 Pa k = 1.38 x 10⁻²³ J/K g = 9.8 m/s² Mair = 28.96 g/mol Assume temperature at the tropopause is 213K and the air is 20.95% O₂.

A mountain climber's oxygen tank contains 1 lb of oxygen when he begins his trip at sea level where the acceleration of gravity is $32.174 \mathrm{ft} / \mathrm{s}^{2} .$ What is the weight of the oxygen in the tank when he reaches the top of Mt. Everest where the acceleration of gravity is $32.082 \mathrm{ft} / \mathrm{s}^{2} ?$ Assume that no oxygen has been removed from the tank; it will be used on the descent portion of the climb.
