8. Vocabulary & Definition
Conversion Factor: a ratio used to express the same value or quantity in two different units

9. KP #1: Dimensional Analysis
What it is:
the problem solving method we will use to convert one unit of measurement to another
Example: Convert inches to feet
To change from one unit to another we will use a conversion factor:
Examples:
1 min = 60 sec
1 ft = 12 in
KP #1: Dimensional Analysis

10. Turn and Discuss: The Ed White junior class decides to hold a bake sale to raise money for prom next year. If they need 5 dozen cookies to raise enough money, how many cookies do they need to make?
KP #2: Using D.A.

11. You used dimensional analysis to find the answer… and probably didn’t even know it!
5 Dozen Cookies 12 X
60 Cookies
1 Dozen
This is a conversion factor!

12. 1. Draw a box 2. Put what you are given on the top left 3
1. Draw a box 2. Put what you are given on the top left 3. Find the conversion factor and cancel units 4. Multiply across and then divide
KP #2: Using D.A.

13. How many seconds are in 45 minutes?
Example #1
1. Draw a box
2. Put what you are given on the top left
3. Find the conversion factor and cancel units
4. Multiply across and then divide
45 x 60 = 2700 seconds

14. C.F.U. #1 & #2 How many seconds are in 9 minutes?
How many hours are in 6 days?
C.F.U. #1 & #2
1. Draw a box
2. Put what you are given on the top left
3. Find the conversion factor and cancel units
4. Multiply across and then divide

15. KP #3: Moles What it is: A unit of measurement in chemistry
Tells you how much of something you have
1 Mole = Molar Mass
KP #3: Moles
This is the conversion factor we will use

1. Draw a box
2. Put what you are given on the top left
3. Find the conversion factor and cancel units
4. Multiply across and then divide
3.6 x 56 = g

17. C.F.U. #3 How many grams are in 4 moles of Sulfur? 1. Draw a box
2. Put what you are given on the top left
3. Find the conversion factor and cancel units
4. Multiply across and then divide

18. Example #2 How many moles are in 17 grams of Calcium Selenide?
KP #4: Apply D.A. to moles
1. Draw a box
2. Put what you are given on the top left
3. Find the conversion factor and cancel units
4. Multiply across and then divide

19. C.F.U. #4 How many moles are in 36 grams of Water? 1. Draw a box
2. Put what you are given on the top left
3. Find the conversion factor and cancel units
4. Multiply across and then divide
