The abundance of ozone is typically inferred from measurements of UV absorption and is often expressed in terms of Dobson units: 1 DU is equivalent to a layer of pure ozone 103 cm thick at 1 atm and 0°C. Given a molar absorption coefficient of 476 dm³ mol 1 cm 1, compute the absorbance of UV radiation for the ozone values shown below. (a) 320. DU (a typical value) mol-1 4.0 15.2 x (b) 150. DU (a value reached during seasonal Antarctic ozone depletions)
