Transcribed Image Text:Constants I
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 (CF2 Cl2).
These air conditioners are recharged from
stockpiled supplies of CFC-12. Suppose that 100
million automobiles each contain 1.3 kg of CFC-12
and leak 25 % of their CFC-12 into the atmosphere
Part A
How much chlorine, in kg, is added to the atmosphere each year due to these air conditioners?
Express your answer using two significant figures.
per year.

kg/yr
Expert Solution
Step 1
The number of cars that using CFC-12 is = 100 million
The mass of CFC-12 used by each car is = 1.3 kg
The leakage of CFC-12 per year is = 25 %
The molecular formula of CFC-12 is = CF2Cl2
