Problem: Because of increasing evidence of damage to the ozone layer, chlorofluorocarbon (CFC) production was banned in 1996. However, many older cars still have air conditioners that use CFC-12 (CF2Cl2). These air conditioners are recharged from stockpiled supplies of CFC-12. Suppose that 100 million automobiles each contain 1.2 kg of CFC-12 and leak 26 % of their CFC-12 into the atmosphere per year.How much chlorine, in kg, is added to the atmosphere each year due to these air conditioners?

FREE Expert Solution

We are asked to calculate the amount of Chlorine (in kg) is added to the atmosphere each year due to the cars that contains CFC-12 as conditioners.


We know that:

  • each car has 1.2 kg of CFC-12
  • each car leaks 26% of CFC-12 per year
  • there are 100 million cars → 1.0x10cars

Because of increasing evidence of damage to the ozone layer, chlorofluorocarbon (CFC) production was banned in 1996. However, many older cars still have air conditioners that use CFC-12 (CF2Cl2). These air conditioners are recharged from stockpiled supplies of CFC-12. Suppose that 100 million automobiles each contain 1.2 kg of CFC-12 and leak 26 % of their CFC-12 into the atmosphere per year.

How much chlorine, in kg, is added to the atmosphere each year due to these air conditioners?
