At an altitude of 22km, the concentration of O3 in the stratosphere is 2.92ppm (50C and 0.0500atm). a) Calculate the density of O3 in molec. cm3 units at 22km altitude. b) Calculate the concentration of O3 in gm3 at 22km altitude. 2. At an altitude of 33km, the concentration of O2 in the stratosphere is 6.76ppm (-25 C and 0.0100atm ). a) Calculate the density of O2 in molec. cm4 units at 33km altitude. b) Calculate the concentration of O3 in gm4 at 33km altitude. 3. Compare the answers for question 1 with those from question 2. Explain in a few sentences why the concentrations in molec. cm3 units follow a different trend than the ppm concentrations (i.e. one is larger at the higher altitude, the other is larger at the lower altitude)
