# Problem: The average person breathes 14 times per minute. Each breath is about 350 mL. The exhaled air is about 5.3% carbon dioxide. In all about 5,300 moles (44 g in a mole) of carbon dioxide are exhaled per person per year. If the human population of the earth is 7.2 x 109, how many kilograms of carbon dioxide are released into the atmosphere by all people in a year?
