Ozone is depleted in the stratosphere by chlorine from CF3Cl according to the following set of equations:
CF3Cl+UV light-->CF3+Cl
Cl+O3-->ClO+O2
O3+UV light-->O2+O
ClO+O-->Cl+O2

What total volume of ozone measured at a pressure of 22.0 mmHg and a temperature of 220 K can be destroyed when all of the chlorine from 20.0 g of CF3Cl goes through ten cycles of the above reactions?
