Roughly 3.97 % of what you exhale is carbon dioxide. Assume that 22.4 L is the volume of 1 mole (6.02·1023 molecules) of carbon dioxide and that you exhale 0.539 L per breath.
a) Calculate how many carbon dioxide molecules you breathe out each day. Assume that on average a person exhales 23500 times per day.
b) If each mole of carbon dioxide has a mass of 44.01 g, how many kilograms of carbon dioxide do you exhale in a year?
