The ozone layer is about 20 km thick, has an average total pressureof 10 mm Hg(1.3 * 10^-2 atm ) , and has an average temperature of 230 K. The partial pressure of ozone in the layer is only about 1.2 * 10^-6 mm Hg( 1.6 * 10^-9 atm ).
How many meters thick would the layer be if all the ozone contained in it were compressed into a thin layer of pure O3 at STP?
I know you have to use the PV= nRT formula and Dalton's partial pressure, but i dont know to to integrated Daltons Partial pressure law into this question.
