Click the  play button. When finished,

click "Go to Sim". Choose an object. Read 
the 
question carefully. Open the "Mole Map" 
to see 
what the conversion factors are. Enter 
the 
starting value in the box in the lower left 
hand 
corner. Click the arrow and choose the 
correct 
unit and substance. Find the conversion 
factor 
that has the correct units and substance 
and 
drag it into the "Drop Conversion Factor" Box. 

Click the  to flip the conversion factor if 

needed. If your answer is correct, it will turn 
green.

Go through different objects until you're 
sure you know how to convert from 
moles to a number, moles to  grams and
vice versa. Speak with me 
if you're still unsure or would like me 
to help you go through this. Take a 
screenshot of the example you chose 
and email to me.

                                     DUE 10/30
Read the article. Go to this week's 
folder to try a fingerprint exercise. 
Instructions are in the folder.

Topics will include both lecture and lab materials FOLLOWING the first midterm. Format will be the same. 

Topics may include:

concepts of chromatography; the chromatography lab

basics of forensic drugs and testing

acid, base, pH, indicators

fingerprint identification - patterns, minutiae, ridge count, reliability

molar mass, grams to mole and vice versa

conversion factors

properties and differences of subatomic particles
