Ozone is depleted in the stratosphere by chlorine from CF3Cl according to the following set of equations:
CF3Cl + UV light --> Cf3 + ClCl + O3 --> ClO + O2O3 + UV light --> O2 + OClO + O --> Cl + O2
What total volume of ozone measured at a pressure of 27.0 mmHg and a temperature of 218 K can be destroyed when all of the chlorine from 20.0 g of CF3Cl goes through ten cycles of the above reactions?
