Concentration of Solutions

Problem Set Answers - Proper sig figs may not be represented here. I believe they are all within reason.
8.8a 4 M, b 0.25 M, c 1 M
8.9 504 g HNO3, 144 g glucose
8.10 0.2 M
8.11  4 M Na+  (Please include the M of the sodium carbonate solution.)
8.12 1.6 M
8.13 0.47 molal
8.14 Use the density of benzene to calculate mass.   0.284 molal
Review your quiz with molarity, molality, mole fraction, and % mass for the QUIZ 3/2

Materials Science is FUN!

Thank you to our guest speaker today! Here's the butterfly video he mentioned!
Clemson has a great materials science program and we enjoyed seeing plasma created right before our eyes!

GREAT STOICH TESTS

GREAT WORK ODY on STOICH and predicting products! Let's make our next test grades as good guys! Honors, I know your tests Wed will show your hard work too! Stoichiometry uses dimensional analysis and it's a skill we call on the rest of the year so I am so pleased when you get it! And if you didn't we'll work on it; come see me to schedule a day to work one on one. Next chapter is SOLUTIONS. Well, not exactly next. We are starting to discuss solutions, but we will be going to the computer lab to begin working on the open book edmodo quizzes. If you have time to go ahead and read chapter 6, it will make your work load lighter this week. Have a great weekend. Read your cereal box or shampoo bottle if you don't do any other chemistry.

Types of Reactions Lab

Dropbox

I love Dropbox.com because it is so easy to put a file in my public folder and then copy a link to it! I also love that every document I saved last night is right at my fingertips this morning with no additional clicks.

Studying with the TEST in mind: Empirical Formulas

Did you review your polyatomic ions? Please do! Click here to study with quizlet.
Empirical - should make you think of lab or experimental data.  However, empirical formulas are those that are in simplest terms.
*Remember the steps for finding empirical formula:
               1. Find grams. 2. Find moles. 3. Find subscripts. (Compare moles.)
