The Stoichiometry of Driving and its Environmental impact Lab: In application lab you may collaborate with another student but, you must use your personal data from the pre-lab assignment. As you complete the activity, please make sure the work for any conversions are done using unit conversion or dimensional analysis (include units with every number). For stoichiometry calculations make sure you include a unit and identifier for every value placed in the calculation string. Before you begin your calculations, go through the pre-lab with your partner(s) and make sure you came up with the same answers for questions 1-5. If there are any differences, discuss, research and come to an agreed upon value for each answer... find the correct answer, don't just pick one from the group without verifying its correctness. Using the miles per gallon of your vehicle, determine the gallons of gasoline you need to last you a typical week. How many grams of CO₂ would you produce in a typical week? (Refer to the pre-lab questions and your reaction equation to find the relationships needed to complete this stoichiometry calculation...to receive maximum points you must set it up in a single calculation string) Based on your average vehicle usage, how many liters of air would you use in a week (use the % composition of air and the average daily high temperature from the week that you collected your data)

The Stoichiometry of Driving and its Environmental impact Lab:
In application lab you may collaborate with another student but, you must use your personal data from the pre-lab
assignment. As you complete the activity, please make sure the work for any conversions are done using unit conversion
or dimensional analysis (include units with every number). For stoichiometry calculations make sure you include a unit
and identifier for every value placed in the calculation string.
Before you begin your calculations, go through the pre-lab with your partner(s) and make sure you came up with the
same answers for questions 1-5. If there are any differences, discuss, research and come to an agreed upon value for
each answer...find the correct answer, don't just pick one from the group without verifying its correctness.
Using the miles per gallon of your vehicle, determine the gallons of gasoline you need to last you a typical week.
How many grams of CO₂ would you produce in a typical week? (Refer to the pre-lab questions and your reaction
equation to find the relationships needed to complete this stoichiometry calculation...to receive maximum points you
must set it up in a single calculation string)

Based on your average vehicle usage, how many liters of air would you use in a week (use the % composition of air and
the average daily high temperature from the week that you collected your data)

what you can realistically do to offset your output. You will need to do some data collection this week so that we can
problem we are going to determine how much of an impact your driving actually has on the environment and
calculate your actual impact and how to offset it. You must collect and use your own actual data. If any data is copied
both individuals with the identical data will earn a zero on this lab assessment. You may discuss how to solve the
problems but, you may not copy anyone's work.
