p = 1 atm and T = 298 K using the ideal gas equation. (b) The atmospheric content of CO2 is about 360 ppmv (parts per million by volume). Assuming a pressure of 1 atm, estimate the amount of CO2 in a 10 km layer of the atmosphere at the surface of the earth. The radius of earth is 6370 km. (The total amount of CO2 in the atmosphere is about 6 × 1016 moles) (c) The atmospheric content of O2 is 20.946% by vol- ume. Using the results in part (b), estimate the amount of O2 in the atmosphere. (d) Life on earth consumes
(a) Calculate the number of moles of gas per cubic meter of atmosphere at p = 1 atm and T = 298 K using the ideal gas equation.
(b) The atmospheric content of CO2 is about 360 ppmv (parts per million by volume). Assuming a pressure of 1 atm, estimate the amount of CO2 in a 10 km layer of the atmosphere at the surface of the earth. The radius of earth is 6370 km. (The total amount of CO2 in the atmosphere is about 6 × 1016 moles)
(c) The atmospheric content of O2 is 20.946% by vol- ume. Using the results in part (b), estimate the amount of O2 in the atmosphere.
(d) Life on earth consumes about 0.47 × 1016 moles of O2 per year. If the photosynthetic production of O2 were to suddenly stop, how long would the oxygen in the atmosphere last at the present rate of consump- tion?
