Average Atomic Mass

We will have a quiz tomorrow over average atomic mass and atomic structure. It will be a short quiz and fairly simple. Attached is the answers for the average atomic mass worksheet. There will be an opportunity to ask questions before the quiz.

Balancing Equations and Stoichiometry

Don’t forget we will have a test over Nomenclature on Tuesday. On Thursday, we will have a quiz over balancing equations and stoichiometry. Below is the answer key for the stoichiometry and balancing equations assignments that I gave out on Friday.

Dimensional Analysis

Below is the key for the dimensional analysis homework. Tomorrow we will have a quiz over dimensional analysis. You will be able to ask questions over the homework before the quiz.

Don’t forget we have our Math in Chemistry test on Wednesday.

Sig Fig Worksheets

Attached are the answer keys for the sig fig worksheets I gave out in class today. Remember I will not be taking a grade on these worksheets. But, we will have a quiz next time in class that will cover sig figs, scientific notation, and reading instruments with sig figs.

More Nomenclature Worksheets

The post prior to this one has the answers to the nomenclature sheets that I took up for a grade. This post contains the answer sheets for the optional worksheets that I gave out in class.

Summer Assignment Information

Below is the information about summer assignments for all AP Chemistry classes.


In order to complete the Quest assignments, you will need to register or reactivate your Quest account. To do this, you will need to visit the UT Quest website. Please try to get this taken care of before the school year ends. It will be difficult for me to help you during the summer with Quest issues in a timely manner. I cannot access UT Quest IDs or passwords for you.

Once you get into Quest, you need to enroll in my Quest course. Please use the following information to enroll in my course:

Semester: Summer 2019

Course Name: APCHEM2019SUM

Or use the following link to access the course: https://quest.cns.utexas.edu/student/courses/enroll_by_link?courseunique=245499 

REMEMBER: Quest assignments will not open until July 20th. Before completing the Quest assignments you should read through the document containing Quest information. This document is also on the disk if you have trouble accessing it here.

  1. Summer instructions – copy of the original letter that was given out at end of year meeting
  2. Quest Online Info
  3. List of Ions
  4. Lab Equipment and Apparatus
  5. Solubility in Water
  6. Safety Rules for Chemistry
  7. Equipment Use
  8. Student Notes over Chemical Foundations, Atoms, Molecules, and Ions, and Stoichiometry

If you are having trouble answer questions and do not find the book or the above resources helpful, here are a few websites that I recommend are:

Khan Academy AP Chemistry website

Bozeman Science AP Chemistry website

Crash Course AP Chemistry Playlist

I can be contacted via email if you have questions. Please note that I typically only check email once a week during the summer so it might take me a little while to get back with you. Please be patient.
