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. Using glucose as an example of food, calculate the annual human production of CO2 in grams, assuming that each person consumes 5.0 × 10^2 grams of glucose per day. The world's population is 7.2 billion, and there are 365 days in a year.
Dimensional Analysis is a way of doing numerical "book-keeping"
when converting quantities or performing calculations.
• When converting quantities from one unit to another,
conversion factors are used.
Solving with Dimensional Analysis and Multiple Units:
If I am in Canada where the price of gas is $1.022 USD·L1, how
much will it cost me to fill up my gas tank if I travelled 125 km?
• Let's also assume that my car gets
an average of 30.0 miles/gallon.
