Answer :
Answer:
The annual production of carbon dioxide is [tex]9.12\times 10^{10} kg[/tex].
Explanation:
Distance covered by each car = 5790 miles
Rate of consumption of gasoline =24. mile/gal
For every 24.1 mile 1 gallon of gasoline is used
Gasoline used by a single car by travelling 5790 miles =
[tex]\frac{1}{24.1}\times 5790 mile=240.24 gal[/tex]
Number of cars in the United states = 40.0 million = [tex]4\times 10^7[/tex]
Total gallons of gasoline consumed by 40 million cars = [tex]4\times 10^7\times 240.24 gal=9.60\times 10^9 gal[/tex]
1 gallon of gasoline produces = 9.50 kg of [tex]CO_2[/tex]
Then [tex]9.60\times 10^9 gal[/tex] of gasoline will produce:
[tex]9.60\times 10^9\times 9.50 kg =9.12\times 10^{10} kg[/tex] of [tex]CO_2[/tex]
The annual production of carbon dioxide is [tex]9.12\times 10^{10} kg[/tex].
