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 6950 mi at a consumption rate of 19.0 miles per gallon. Enter
your answer in scientific notation.
