CHM 1020

Project #2: Measurement via Gasoline Project

Assignment & Data Collection/Presentation:
In Chemistry we collect data in the laboratory while performing an experiment. Our second project concerns measurement and data collection in the field (CHM 1020 has no lab component). As an experiment you can do from the 1st week to the last, we can find out what your energy consumption and cost are for driving a car. So here is the project which we will start ASAP and finish the last week of the term.

During the first weeks of class you need to fill your gasoline tank in your car*. During the course you will keep a
record of all purchases of gasoline noting dates, price, amount, cost and odometer reading. Get receipts and/or keep a diary in your vehicle. Then transfer each purchase to a data page or in a spreadsheet. Collecting the data is worth (10 points) and presenting the data collected is worth (5 Points) which is three fourths of the grade or 15 points. This experiment is equivalent to four small projects as it is an intense 12-14 week exercise in data collection for 20 points. 

During the last weeks, you fill your tank again and record the data*.

The chemical reaction for combusting gasoline is:


2 C8H18 (l) + 25 O2 (g) 16 CO2 (g) + 18 H2O (g)
(Burn 1 gallon put 18.7 Lbs CO2 in the environment!)


In Chapter 9 we will prove the 18.7 lb/gallon statement when we study chemical reactions and mass stoichiometry

*You need to only fill the tank twice, at the beginning and at the end of the project. You will not use the first fill-up in your calculations, except odometer reading. Why?
