Question

Be sure to answer all parts. One gallon of gasoline in an automobiles engine produces on average 9.50 kg of carbon dioxide, which is a greenhouse gas; that is, it promotes the warming of Earth's atmosphere. Calculate the annual production of carbon dioxide in kilograms if there are exactly 40.0 million cars in the United States and each car covers a distance of 5790 mi at a consumption rate of 24.1 miles per gallon. Enter your answer in scientific notation. × 10 kg

Answer 1

Answer:

The annual production of carbon dioxide is $9.12\times 10^{10} kg$.

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 =

$\frac{1}{24.1}\times 5790 mile=240.24 gal$

Number of cars in the United states = 40.0 million = $4\times 10^7$

Total gallons of gasoline consumed by 40 million cars = $4\times 10^7\times 240.24 gal=9.60\times 10^9 gal$

1 gallon of gasoline produces = 9.50 kg of $CO_2$

Then $9.60\times 10^9 gal$ of gasoline will produce:

$9.60\times 10^9\times 9.50 kg =9.12\times 10^{10} kg$ of $CO_2$

The annual production of carbon dioxide is $9.12\times 10^{10} kg$.
