Carbon dioxide (CO2) is the gas that is mainly responsible for global warming (the greenhouse effect). The burning of fossil fuels is a major cause of the increased concentration of CO2 in the atmosphere. Carbon dioxide is also the end product of metabolism.
C6H12O6 + 6 O2 → 6 CO2 + 6 H2O
Using glucose as an example of food, calculate the annual human production of CO2 in grams, assuming that each person consumes 7.0 multiplied by 102 g of glucose per day. The world's population is 6.5 billion, and there are 365 days in a year.
this problem requires the use of dimensional analysis (the conversion of units using relations expressed as ratios) and it requires stoichiometry.
I. amt of C
6H
12O
6 consumed (1 person/1 day) = 7.0x102g = 714g C
6H
12O
6II. convert mass of C
6H
12O
6 consumed (1 person/1 day) to moles.
III. using stoichiometry convert the moles of C
6H
12O
6 consumed (1 person/1 day) to CO
2 and then convert from moles of CO2 to mass of CO2. ****REFER TO YOUR EQUATION*****
IV. CO
2 (human annual production) = mass of CO
2 produced by one person in one day times the world population times the number of days in a year
