Question

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 (CF2C2). These air conditioners are recharged from stockpiled supplies of CFC-12. Suppose that 100 million automobiles each contain 1.0 kg of CFC-12 and leak 29% 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?
