Unformatted text preview: efore, fraction of ozone below inversion height = ⁄ = 1.25 %. 3. If the overall global average ozone concentration is 300 DU, calculate the approximate number of ozone molecules in the atmosphere at any given time Solution #3: Overall global average ozone concentration = 300 DU Assuming pressure = 1atm and temperature = 273 K Now, 300 DU = 3 mm of thickness of pure ozone molecules occupying a vertical column of air from earth's surface to top of stratosphere. 1 DU = 2.69 molecules per Hence, 300 DU = 300 2.69 of earth's crust molecules per of earth's crust = 8.07 molecules of ozone per of earth's crust Approximate number of ozone molecules in atmosphere at any given time = 8.07 km. surface...
